Question: What is the name of the wide-body twin-engine jet airliner that use the design of Richard Clarkson in its development?

Context paragraphs:
Richard Clarkson: Richard Milroy Clarkson OBE FCGI FRAeS (14 July 1904 – 7 October 1996) was a British aeronautical engineer with de Havilland, then Hawker Siddeley.  He designed the HS121 Trident, which was subsequently taken as template for the Airbus A300 in the late 1960s.

List of Airbus A330 operators: The Airbus A330 is a wide-body twin-engine jet airliner made by Airbus.  Versions of the A330 have a range of 7400 to and can accommodate up to 335 passengers in a two-class layout or carry 70 t of cargo.

Airbus A300: The Airbus A300 is a wide-body twin-engine jet airliner that was developed and manufactured by Airbus.  Formally announced in 1969 and first flying in October 1972, it holds the distinction of being the world's first twin-engined widebody airliner; it was also the first product of Airbus Industrie, a consortium of European aerospace manufacturers, now a subsidiary of Airbus.  The A300 can typically seat 266 passengers in a two-class layout, with a maximum range of 4070 nmi when fully loaded, depending on model.

Boeing 757: The Boeing 757 is a mid-size, narrow-body twin-engine jet airliner that was designed and built by Boeing Commercial Airplanes.  It is the manufacturer's largest single-aisle passenger aircraft and was produced from 1981 to 2004.  The twinjet has a two-crew member glass cockpit, turbofan engines of sufficient power to allow takeoffs from relatively short runways and higher altitudes, a conventional tail and, for reduced aerodynamic drag, a supercritical wing design.  Intended to replace the smaller three-engine 727 on short and medium routes, the 757 can carry 200 to 295 passengers for a maximum of 3150 to , depending on variant.  The 757 was designed concurrently with a wide-body twinjet, the 767, and owing to shared features pilots can obtain a common type rating that allows them to operate both aircraft.

Airbus A330: The Airbus A330 is a medium- to long-range wide-body twin-engine jet airliner made by Airbus.  Versions of the A330 have a range of 5000 to and can accommodate up to 335 passengers in a two-class layout or carry 70 t of cargo.

Avro Canada C102 Jetliner: The Avro C102 Jetliner was a Canadian prototype medium-range turbojet-powered jet airliner built by Avro Canada in 1949.  It was beaten to the air by only 13 days by the de Havilland Comet, thereby becoming the second jet airliner in the world.  The name "Jetliner" was chosen as a shortening of the term "jet airliner", a term which is still in popular usage in Canada and the United States.  The aircraft was considered suitable for busy routes along the US eastern seaboard and garnered intense interest, notably from Howard Hughes who even offered to start production under license.  However continued delays in Avro's all-weather interceptor project, the Avro CF-100, led to an order to stop working on the project in 1951, with the prototype Jetliner later cut up for scrap.

List of Boeing 777 operators: The Boeing 777 is a long-range wide-body twin-engine jet airliner designed and manufactured by Boeing Commercial Airplanes, the commercial business unit of Boeing.  Commonly referred to as "Triple Seven", it is the largest twinjet and the world's longest-range airliner.  The 777 can accommodate between 301 and 365 passengers in a three-class layout, and has a range of 5235 to , depending on the model.  Developed in consultation with eight major airlines, the 777 was designed to replace older wide-body airliners and bridge the capacity difference between the 767 and 747.

Boeing 767: The Boeing 767 is a mid- to large-size, mid- to long-range, wide-body twin-engine jet airliner built by Boeing Commercial Airplanes.  It was Boeing's first wide-body twinjet and its first airliner with a two-crew glass cockpit.  The aircraft has two turbofan engines, a conventional tail, and, for reduced aerodynamic drag, a supercritical wing design.  Designed as a smaller wide-body airliner than earlier aircraft such as the 747, the 767 has seating capacity for 181 to 375 people, and a design range of 3850 to , depending on variant.  Development of the 767 occurred in tandem with a narrow-body twinjet, the 757, resulting in shared design features which allow pilots to obtain a common type rating to operate both aircraft.

Boeing 777: The Boeing 777 is a family of long-range wide-body twin-engine jet airliners developed and manufactured by Boeing Commercial Airplanes.  It is the world's largest twinjet and has a typical seating capacity of 314 to 396 passengers, with a range of 5240 to .  Commonly referred to as the "Triple Seven", its distinguishing features include the largest-diameter turbofan engines of any aircraft, six wheels on each main landing gear, fully circular fuselage cross-section, and a blade-shaped tail cone.  Developed in consultation with eight major airlines, the 777 was designed to replace older wide-body airliners and bridge the capacity difference between Boeing's 767 and 747.  As Boeing's first fly-by-wire airliner, it has computer-mediated controls.  It was also the first commercial aircraft to be designed entirely with computer-aided design.

Boeing 787 Dreamliner: The Boeing 787 Dreamliner is an American long-haul, mid-size widebody, twin-engine jet airliner made by Boeing Commercial Airplanes.  Its variants seat 242 to 335 passengers in typical three-class seating configurations.  It is the first airliner with the use of composite materials as the primary material in the construction of its airframe.  The 787 was designed to be 20% more fuel efficient than the Boeing 767, which it was intended to replace.  The 787 Dreamliner's distinguishing features include mostly electrical flight systems, raked wingtips, and noise-reducing chevrons on its engine nacelles.  It shares a common type rating with the larger Boeing 777 to allow qualified pilots to operate both models.
