Assertion (A): An electron has a high potential energy when it is at a location associated with a more negative value of potential, and a low potential energy when at a location associated with a more positive potential.
Reason (R): Electrons move from a region of higher potential to region of lower potential.

a)both assertion and reason are correct and reason is the correct explanation of assertion
b)both assertion and reason are correct but the reason is not the correct explanation for assertion
c) assertion is correct but reason is false
d) assertion is incorrect but reason is correct
