The Electric Potential Due to a Dipole at a Point

The electric potential due to a dipole at a point situated at a distance d, larger than the distance between the dipole's charges, is larger when

A) the point is closer to the positive charge than to the negative charge.
B) the point is located symmetrically between the positive and negative charges.
C) the point is closer to the negative charge than to the positive charge.
D) All of the previous responses are correct because the electric potential is constant all around the dipole.
E) None of the previous responses is correct.
