The Figure Shows a Series Ac Circuit

The figure shows a series ac circuit. The inductor has a reactance of 50 Ω and an inductance of 220 mH. An 80-Ω resistor and a capacitor whose reactance is 160 Ω are also in the circuit, and the rms current in the circuit is 2.2 A. What is the voltage amplitude across the capacitor?

A) 500 V
B) 350 V
C) 630 V
D) 770 V
E) 210 V
