Question: The pepperoni roll is a snack popular in West Virginia and some nearby regions of the Appalachian Mountains such as Appalachian Ohio is a bioregion and political unit in the southeastern part of the state of Ohio, characterized by the western foothills of the Appalachian Mountains, and Appalachian Plateau, in which country?

Context paragraphs:
Pepperoni roll: The pepperoni roll is a snack popular in West Virginia and some nearby regions of the Appalachian Mountains such as Western Pennsylvania, Western Maryland, and Appalachian Ohio.  It is ubiquitous in West Virginia, particularly in convenience stores, and is arguably the food most closely associated with the state.

Allegheny Front: The Allegheny Front is the major southeast- or east-facing escarpment in the Allegheny Mountains in southern Pennsylvania, western Maryland, and eastern West Virginia, USA.  The Allegheny Front forms the boundary between the Ridge-and-Valley Appalachians to its east and the Appalachian Plateau (locally called the Allegheny Plateau) to its west.  The Front is closely associated with the Appalachian Mountains' Eastern Continental Divide, which in this area divides the waters of the Ohio/Mississippi river system, flowing to the Gulf of Mexico, from rivers flowing into Chesapeake Bay and from there into the Atlantic Ocean.

Wheeling, West Virginia: Wheeling is a city in Ohio and Marshall counties in the U.S. state of West Virginia.  Located almost entirely in Ohio County, of which it is the county seat, it lies along the Ohio River in the foothills of the Appalachian Mountains.  Wheeling was originally a settlement in the British colony of Virginia and later an important city in the Commonwealth of Virginia.  Wheeling was the first state capital of West Virginia.  Due to its location along major transportation routes, including the Ohio River, National Road, and the B&O Railroad, Wheeling became a manufacturing center in the late nineteenth century.  After experiencing the closing of factories and substantial population loss following World War II, Wheeling's major industries now include healthcare, education, law and legal services, entertainment and tourism, and energy.

Appalachian Ohio: Appalachian Ohio is a bioregion and political unit in the southeastern part of the U.S. state of Ohio, characterized by the western foothills of the Appalachian Mountains and Appalachian Plateau.  The Appalachian Regional Commission defines the region as consisting of thirty-two counties.  This region roughly overlaps with the Appalachian mixed-mesophytic forests, which begin in southeast Ohio and southwest Pennsylvania and continue to north Georgia and Alabama.  The mixed-mesophytic forest is found only in Central and Southern Appalachia and eastern/central China.  It is one of the most biodiverse temperate forests in the world.

Cumberland Plateau: The Cumberland Plateau is the southern part of the Appalachian Plateau in the Appalachian Mountains of the United States.  It includes much of eastern Kentucky and Tennessee, and portions of northern Alabama and northwest Georgia.  The terms "Allegheny Plateau" and the "Cumberland Plateau" both refer to the dissected plateau lands lying west of the main Appalachian Mountains.  The terms stem from historical usage rather than geological difference, so there is no strict dividing line between the two.  Two major rivers share the names of the plateaus, with the Allegheny River rising in the Allegheny Plateau and the Cumberland River rising in the Cumberland Plateau in Harlan County, Kentucky.

Ridge-and-Valley Appalachians: The Ridge-and-Valley Appalachians, also called the Ridge and Valley Province or the Valley and Ridge Appalachians, are a physiographic province of the larger Appalachian division and are also a belt within the Appalachian Mountains extending from southeastern New York through northwestern New Jersey, westward into Pennsylvania and southward into Maryland, West Virginia, Virginia, Kentucky, Tennessee, Georgia and Alabama.  They form a broad arc between the Blue Ridge Mountains and the Appalachian Plateau physiographic province (the Allegheny and Cumberland Plateaus).  They are characterized by long, even ridges, with long, continuous valleys in between.

Wallkill Valley: The Wallkill Valley is a broad valley extending through southeastern New York and northwestern New Jersey.  It is composed of rolling hills, plains, and swamps (including the Black Dirt Region) surrounding the Wallkill River.  The valley is a subdivision of the larger Hudson Valley, bound to the west by the Shawangunk Ridge/Kittatinny Mountains and to the east by the Marlboro Mountains and New York–New Jersey Highlands.  The northern Wallkill Valley is sometimes associated with the greater Catskills region, although it is geographically separated from the Catskill Mountains by the Shawangunk Ridge and Rondout Valley.  In a broader sense, the Wallkill Valley is part of the Ridge-and-Valley physiographic province of the Appalachian Mountains, while the Catskills further to the north and west are part of the Appalachian Plateau.

Jackson Lake State Park (Ohio): Jackson Lake State Park is a 349 acre Ohio state park in Jackson County, Ohio, in the United States.  The park was established as a state park in 1979.  It had previously been a "state reserve", similar to a park but with less development.  The forests in and around Jackson Lake State Park were previously harvested to fire the furnaces of numerous iron works that were located in southern Ohio in the western foothills of the Appalachian Mountains.  Recreational activities available at the park include camping, boating, fishing, swimming and picnicking.

Country Club Bakery: Country Club Bakery, located in Fairmont, West Virginia, USA, is a small family owned bakery that is significant because it is the home of the pepperoni roll.  The bakery is located on Country Club Road, but the original bakery (where the pepperoni roll was invented) was located on Robinson Street.  The pepperoni roll is a snack popular in West Virginia and some nearby regions of the Appalachian Mountains.  Ubiquitous in West Virginia (particularly in convenience stores), but typically little known elsewhere, it is arguably the food most closely associated with the state (a competitor for this distinction is the ramp).  The first pepperoni rolls were created at the Country Club Bakery in Fairmont, West Virginia by Giuseppe "Joseph" Argiro at the Country Club Bakery in Fairmont in 1927, some argue that it was not invented until the 1940s, but no one disputes that they originated at the Country Club Bakery.  Fairmont, West Virginia, claims the title of "Pepperoni Roll Capital of the World."

Huntington, West Virginia: Huntington is a city in Cabell County and Wayne County in the U.S. state of West Virginia.  It is the county seat of Cabell County, and largest city in the Huntington-Ashland, WV-KY-OH Metropolitan Statistical Area, sometimes referred to as the Tri-State Area.  A historic and bustling city of commerce and heavy industry, Huntington has long-flourished due to its ideal location on the Ohio River at the mouth of the Guyandotte River.  It is home to the Port of Huntington Tri-state, the busiest inland port in the United States.  Surrounded by extensive natural resources, the industrial sector is based in coal, oil, chemicals and steel all of which support Huntington's diversified economy.  The city is a vital rail-to-river transfer point for the marine transportation industry.  Also, it is considered a scenic locale in the western foothills of the Appalachian Mountains.  This location was selected by Collis Potter Huntington as ideal for the western terminus of the Chesapeake and Ohio Railway, the predecessor of what would become CSX Transportation which still operates CSX Transportation-Huntington Division in the city to date.  The railroad founded Huntington as one of the nation's first planned communities to facilitate the railroad and other transportation related industries at the railways western terminus.  Developing fast after the railroad's completion in 1871, the site was previously a collection of agricultural homesteads, and is eponymously named for the railroad company's founder Collis Potter Huntington.  The first identifiable permanent settlement, Holderby's Landing, was founded in 1775 in the Colony of Virginia although the site had been sparsely settled by the French as early as 1609.  With the exception of the neighborhoods of Westmoreland and Spring Valley, most of the city is in Cabell County.
