If the potential difference across a plane parallel plate capacitor is doubled then the potential energy of the capacitor is doubled then the potential energy of the capacitor becomes four times under all conditions
The potential energy `U` stored in the capacitor is `U=(1)/(2) CV^(2)`, where `C` and `V` have usual meaning.

Options

A. Both A and R false
B. Both A and R true and R is not correct reason for A
C. A is true and R is false
D. Both A and R are true and R is correct reason of A.
