A small signal voltage $e=e_0 \sin \omega t$ is applied across an ideal capacitor of capacitance C. The correct statement is:

Phase difference between Current I(t) and Voltage V(t) is zero. Capacitor does not consume any energy from the source of emf over a complete cycle. Current I(t) lags behind the voltage V(t) by $\frac{\pi}{2}$ Current I(t) leads the voltage V(t) by $\pi$

Capacitor does not consume any energy from the source of emf over a complete cycle.

The correct answer is Option (2) → Capacitor does not consume any energy from the source of emf over a complete cycle.
