Answer 1

The correct answer is option 4):(spheres)

Concept:

The surface on which the potential at each point is the same/equal is called the equipotential surface.
The electric field lines will be perpendicular to the equipotential surface always.
In the case of a point charge, due to symmetry, the electric field at the surface of the sphere will be the same for the whole surface.
Thus it will be an equipotential surface where a charge is at the centre of the sphere. Hence option 4 is correct.
