Correct option (a) Between A and B gravitational field strength is zero.

(b) Between A and B gravitational potential is constant

(c) There will be two point one lying between B and C and other lying between C and infinity where gravitational field strength are same.

Explanation :

As there is no mass inside B, So, field between A to B is zero, i,e,. potential between  A to B is constant.

Potential between B and C is not zero at any point.
