Answer:

a,b and c are true.

Explanation:

Following are true statements

a. Electric field lines and Equipotential surfaces are always mutually perpendicular is a true statement.

b. When all charges are at rest, the surface of a conductor is always an equipotential surface.

c. An equipotential surface is a three-dimensional surface on which the electric potential is the same at every point.

Following are False statements

d. The potential energy of a test charge increases as it moves along an equipotential surface.

e. The potential energy of a test charge decreases as it moves along an equipotential surface.

Reason: A t any point in an equipotential surface, the potential is same throughout. There is no increase or decrease in potential energy as the test charge moves in an equipotential environment.
