A. 90°
B. 0°
C. 60°
D. None of these

Answer 1

Hint: The Prime Meridian is the starting point for measuring distance both east and west around the Earth. The prime meridian is used as a geographical reference line which passes through the Royal Observatory, Greenwich, in London, England.

Complete answer:
It was first established by Sir George Airy in 1851.By 1884, over two-thirds of all ships and tonnage used it as the reference meridian on their charts and maps. Prime Merdian's value is 0° longitude and from it, we count 180° eastward as well as 180° westward. The Prime Meridian and 180° meridian divide the earth into two halves, the Eastern Hemisphere and the Western Hemisphere. Together, a prime meridian and its antimeridian form a great circle. The starting point for measuring distance both east and west around the Earth.
Now ,let's see the options:-
90° - As the Prime Meridian's value is zero degrees , therefore it's the incorrect option.
0°- Prime meridian and its antimeridian together form a great circle. This great circle divides the sphere, e.g., Earth, into two hemispheres and the value is 0°. Hence it's the correct answer.
60° - There is no particular name for a 60 degree longitude hence this is an incorrect option.
None of these - As option (B) 0 degree is the correct option hence this is incorrect.

Therefore, the correct answer is option (B).
