In a series L-C-R circuit \( \mathrm{R}=200 \Omega \) and the voltage and the frequency of the main supply is \( 220 \mathrm{~V} \) and 50 \( \mathrm{Hz} \) respectively. On taking out the capacitance from the circuit the current lags behind the voltage by
\( P \) \( 30^{\circ} \). On taking out the inductor from the circuit the current leads the voltage by \( 30^{\circ} \). The power dissipated in the \( \mathrm{L}-\mathrm{C}-\mathrm{R} \) circuit is
(A) \( 305 \mathrm{~W} \)
(B) \( 210 \mathrm{~W} \)
(C) zero
(D) \( 242 \mathrm{~W} \)
