Options
A capacitance
B surface charge density on each plate
C stored energy
Correct Answer
D . C halves (d doubles), so U = Q2/(2C) DOUBLES.
Correct Answer

Option C is the correct answer.

Detailed Explanation

Charge Q is fixed (disconnected). C halves (d doubles), so U = Q2/(2C) DOUBLES.

Hint

Charge Q is fixed (disconnected).
