An example of an equipotential surface in earth is

AA line passing through the centre of the earth connecting two points along the diameter
BA plane that passes through the circular section of the hemisphere of the earth
CA spherical surface at a distance of 1km from the surface of the earth with its centre at centre of earth
Correct Answer
DA plane on the surface of the earth, which is a tangent to the earth

Solution

The potential is seen to be a constant on a sphere at all points. Hence (c) is the correct option
