A small signal voltage $V(t )= V_0 \sin \omega t$ is applied across an ideal capacitor C :

Question

( A ) Current $I(t)$ leads voltage $V(t)$ by $180^o$
( B ) Current $I(t)$, lags voltage $V(t)$ by $90^o$
( C ) Over a full cycle the capacitor C does not consume any energy from the voltage source
( D ) Current $I (t)$ is in phase with voltage $V(t)$
