Electric Potential: Does Energy Increase/Decrease?

[Litcyb]

Homework Statement

As an electron moves from a high potential to a low potential, its electric potential energy?

a) increases
b) remains the same
c) decreases

Homework Equations

we know that

V=U q0
the electric potential = potential energy times the charge.

The Attempt at a Solution

i think the answers is a, since we have to take into account that the charge is negative.
but many people argue other wise. i just want to verify what's the right answer and why.
