Energy in SHM

The quantity which does not vary periodically for a particle performing SHM is

Show answer and solution

Answer: (b)

Displacement, velocity and acceleration all vary sinusoidally with time.
Total energy $KE + PE = \dfrac{1}{2}kA^2$ stays constant.
So the answer is (b) total energy.
