In a full-wave rectifier using two ideal diodes,Vdc & Vm are the dc & peak values of the voltage respectively across a resistive load. If PIV is the peak inverse voltage of the diode, then the appropriate relationships for this rectifier is____________?

A. Vdc = Vm/π, PIV=2Vm
B. Vdc = 2Vm/π, PIV=2vm
C. Vdc = 2Vm/π, PIV=Vm
D. Vdc = Vm/π, PIV=Vm
