Equipotential surfaces are

ASurfaces that are perpendicular to gravitational fields
Correct Answer
BSurfaces that have same mass on top of it
CSurface that have same radius of curvature
DSurfaces that have same gravitational field on it

Solution

Equipotential surfaces are surfaces which have the same value of potential throughout their surface.
For a gravitatiomal field of $$E=\dfrac{GM}{r^2}$$,the potential is $$v=-\dfrac{GM}{r}$$
So,at a particular 'r',the potential remains constant at a value of $$-\dfrac{GM}{r}$$
So equipotential surfaces are circles for the filed of $$E=\dfrac{GM}{r^2}$$
Hence,the field is perpendicular to equipotential surface.
