Hint: In a geographic coordinate system, a prime meridian is the meridian at which longitude. A prime meridian and its anti-meridian, together, form a broad circle.

Complete answer: The value of prime meridian is 0 Degree. A prime meridian is the meridian (a line of longitude) in a geographic organize framework at which longitude is characterized to be 0°.Together, a prime meridian and its enemy of meridian (the 180th meridian in a 360°-framework) structure an incredible circle. This extraordinary circle isolates a spheroid into two sides of the equator. In the event that one uses bearings of East and West from a characterized prime meridian, at that point they can be known as the Eastern Side of the equator and the Western Hemisphere.

The Eastern Side of the equator is a geological term for the half of Earth which is east of the prime meridian (which crosses Greenwich, London, Joined Realm) and west of the antimeridian (which crosses the Pacific Sea and moderately little land from shaft to pole).The Western Side of the equator is a topographical term for the half of Earth which lies west of the prime meridian (which crosses Greenwich, London, Joined Realm) and east of the antimeridian.For Earth's prime meridian, different shows have been utilized or pushed in various districts all through history.

 The most generally utilized present day meridian is the IERS Reference Meridian. It is gotten however goes astray somewhat from the Greenwich Meridian, which was chosen as a worldwide norm in 1884.A prime meridian for a body not tidally bolted (or if nothing else not simultaneous) is eventually subjective, in contrast to an equator, which is controlled by the hub of turn. For divine items that are tidally bolted (all the more explicitly, simultaneous), notwithstanding, their prime meridians are controlled by the face in every case internal of the circle (a planet confronting its star, or a moon confronting its planet), similarly as equators are dictated by turn.

Thus, the answer is option B: 0 degree.

Note: The modern prime meridian, based at the Royal Observatory, Greenwich, was established by Sir George Airy in 1851. As with the Planet, it is important to arbitrarily identify prime meridians.
