Equipotentials at a large distance from a collection of charges, whose total sum is not zero are
(a) spheres. At a large distance, a collection of charges with a nonzero net charge behaves like a point charge, producing spherical equipotential surfaces centered around the effective charge distribution.

The correct answer is (a) spheres.
At a large distance, a collection of charges with a nonzero total sum behaves like a point charge. The equipotential surfaces around a point charge are spherical, centered on the charge. This follows from the equation V= 1/4πϵ Q/r, which depends only on distance r.
