A series LCR circuit is connected to an ac source of frequency $$f$$ and a voltage $$V$$. At this frequency, reactance of the capacitor is 350 ohm while the resistance of the circuit is 180 ohm. Current in the circuit leads the voltage by $$54^\circ$$ and power dissipated in the circuit is 140 watt. Therefore, voltage $$V$$ is

A

250 volt

B

260 volt

C

270 volt

D

280 volt
