i have one physics problem

a circuits consists of a resistor and a capacitor in series with an ac source that supplies an rms voltage of 240 V. At the frequency of the source the reactance of the capacitor is 53.5. The rms current in the circuits is 4.00 A. What is the average power in W supplied by the source?

a. 129

b. 256

c. 435

d. 645

e. 800
