Correct option is D)

By energy stored in a charged conductor Suppose, a conductor of capacity C is charged to a potential V and Q the charge on conductor at a instant. 
The potential of the conductor 

Now, work done in bringing a small charge dQ at this potential is,  
 
Total work done in charging it from 0 to Q is, 


This work is stored as the potential energy.
