0An ac circuit contains a resistance \( R \), capacitance \( C \) and inductance \( L \) in series with a source of emf \( e=e_{0} \sin (\omega t+\phi) \). The current through the circuit is maximum when:
(A) \( \omega^{2}=\mathrm{L} C \)
(B) \( \omega L=\frac{1}{\omega C} \)
(C) \( \mathrm{R}=\mathrm{L}=\mathrm{C} \)
(D) \( \omega=L C R \)
