Mass M is uniformly distributed only on curved surface of a thin hemispherical shell. A, B and C are three points on the circular base of hemisphere, such that A is the centre. Let the gravitational potential at poins A, B and C be `V_(A), V_(B), V_(C)` respectively. Then :
A. `V_(C) gt V_(B) gt V_(C)`
B. `V_(C) gt V_(B) gt V_(A)`
C. `V_(B) gt V_(A)` and `V_(B) gt V_(A)`
D. `V_(A) = V_(B) = V_(C)`
