If Assertion is correct but Reason is incorrect.

(C) The Assertion is correct because if two equipotential surfaces were to intersect,the point of intersection would have two different values of electric potential,which is physically impossible.The Reason is incorrect because equipotential surfaces are not necessarily parallel to each other. For example,for a point charge,the equipotential surfaces are concentric spheres,and for a line charge,they are coaxial cylinders. They can have any shape depending on the charge distribution.
