Suppose Two Charges,one Positive and One Negative,are Separated by a Distance

Multiple Choice

Suppose two charges,one positive and one negative,are separated by a distance d.Where can two equipotential surfaces at different potentials intersect in the region near the charges?

A) halfway between the charges if the charges have the same magnitude
B) closer to the smaller negative charge than the larger positive charge if the charges are not equal
C) Equipotential surfaces at different potentials cannot intersect.
D) closer to the smaller positive charge than the larger negative charge if the charges are not equal
