Information: - The Hunt class is a class of thirteen mine countermeasure vessels of the Royal Navy . As built , they combined the separate roles of the traditional minesweeper and that of the active minehunter in one hull , but later modifications saw the removal of mine - sweeping equipment . They have a secondary role as offshore patrol vessels . - A naval mine is a self-contained explosive device placed in water to damage or destroy surface ships or submarines. Unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, an enemy vessel. Naval mines can be used offensivelyto hamper enemy shipping movements or lock vessels into a harbour; or defensivelyto protect friendly vessels and create "safe" zones. - The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by the English kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years War against the kingdom of France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is known as the Senior Service. - A minehunter is a naval vessel that actively detects and destroys individual naval mines. Minesweepers, on the other hand, clear mined areas as a whole, without prior detection of mines. A vessel that combines both of these roles is known as a mine countermeasures vessel (MCMV). - A mine countermeasures vessel or MCMV is a type of naval ship designed for the location of and destruction of naval mines which combines the role of a minesweeper and minehunter in one hull. The term MCMV is also applied collectively to minehunters and minesweepers. - The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a sovereign country in western Europe. Lying off the north-western coast of the European mainland, it includes the island of Great Britain (the name of which is also loosely applied to the whole country), the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another sovereign statethe Republic of Ireland. Apart from this land border, the UK is surrounded by the Atlantic Ocean, with the North Sea to its east, the English Channel to its south and the Celtic Sea to its south-south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of , the UK is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants. Together, this makes it the fourth most densely populated country in the European Union.

Ques:Information: - GNU is an operating system and an extensive collection of computer software. GNU is composed wholly of free software, most of which is licensed under the GNU Project's own GPL. - Linus Benedict Torvalds (born December 28, 1969) is a Finnish software engineer who is the creator and, for a long time, principal developer, of the Linux kernel; which became the kernel for operating systems such as the Linux operating system, Android and Chrome OS. He also created the distributed revision control system Git and the diving logging and planning software Subsurface. He was honored, along with Shinya Yamanaka, with the 2012 Millennium Technology Prize by the Technology Academy Finland "in recognition of his creation of a new open source operating system for computers leading to the widely used Linux kernel". He is also the recipient of the 2014 IEEE Computer Society Computer Pioneer Award. - Linux (pronounced or, less frequently) is a Unix-like computer operating system assembled under the model of free and open-source software development and distribution. The defining component of Linux is the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. The Free Software Foundation uses the name GNU/Linux to describe the operating system, which has led to some controversy. - Lugaru : The Rabbit 's Foot / luru / is the first commercial video game created by Wolfire Games . It is a cross-platform , 3D action game for Microsoft Windows , AmigaOS 4 , AROS , Mac OS X , and GNU / Linux . It features Turner , an anthropomorphic rabbit with curiously well - developed combat skills . Lugaru was made almost solely by David Rosen , including the game engine , models , animations and story . It was one of the first independently produced video games to employ ragdoll physics . It uses a combat system basing attacks and counters on timing and context rather than different key combinations . It was well reviewed and was fairly well received among the shareware community , especially among Mac users . Tim Soret would later improve the game 's textures , and Wolfire currently sells this version as Lugaru HD . The name Lugaru is a phonetic spelling of '' loup - garou '' , which is French for werewolf . The word '' Lugaru '' is commonly pronounced as loogaroo . David Rosen has announced that Overgrowth ( video game ) will be the sequel to Lugaru . Lugaru uses OpenGL , OpenAL and Simple DirectMedia Layer . - The Free Software Foundation (FSF) is a 501(c)(3) non-profit organization founded by Richard Stallman on 4 October 1985 to support the free software movement, which promotes the universal freedom to study, distribute, create, and modify computer software, with the organization's preference for software being distributed under copyleft ("share alike") terms, such as with its own GNU General Public License. The FSF was incorporated in Massachusetts, USA, where it is also based. - Free and open-source software (FOSS) is computer software that can be classified as both free software and open-source software. That is, anyone is freely licensed to use, copy, study, and change the software in any way, and the source code is openly shared so that people are encouraged to voluntarily improve the design of the software. This is in contrast to proprietary software, where the software is under restrictive copyright and the source code is usually hidden from the users. - Open-source software (OSS) is computer software with its source code made available with a license in which the copyright holder provides the rights to study, change, and distribute the software to anyone and for any purpose. Open-source software may be developed in a collaborative public manner. According to scientists who studied it, open-source software is a prominent example of open collaboration. After reading the paragraphs above, we are interested in knowing the entity with which 'lugaru' exhibits the relationship of 'license'. Find the answer from the choices below. Choices: - copyright - free software - gnu general public license - open source - proprietary software

Ans:
proprietary software
