Four Electrons Move from Point a to Point B in a Uniform

Four electrons move from point A to point B in a uniform electric field as shown below.Rank the electrons in diagrams I through IV by the changes in potential energy from most positive to most negative when traveling from A to B.

A) I = II = III = IV.
B) II = III > I > IV.
C) III > I = IV > II.
D) II > I = IV > III.
E) I > II = III > IV.
