A negative charge is placed between a pair of oppositely charged plates, as shown. Two horizontal parallel plates have a negatively charged sphere labeled X right in between them. The top plate is positive and the bottom plate is negative.

Which best describes the result of moving the charge to the point marked X?

A. Its electric potential energy increases because it has the same electric field.
B. Its electric potential energy increases because the electric field increases.
C. Its electric potential energy stays the same because the electric field increases.
D. Its electric potential energy stays the same because it has the same electric potential.
