In a parallel plate capacitor, the distance between the plates is `d` and potential difference across the plate is `V`. Energy stored per unit volume between the plates of capacitor is
A. `(Q^(2))/(2V^(2))`
B. `(1)/(2)(epsilon_(0)V^(2))/(d^(2))`
C. `(1)/(2)(V^(2))/(epsilon_(0)d^(2))`
D. `(1)/(2)epsilon_(0)(V^(2))/(d)`
