In the first positive cycle, the capacitor will charge till Vm voltage positively and again in negative cycle polarity of the input signal will change and signal negative voltage and capacitor positive voltage will add hence total PIV appear 2Vm.

B is correct since it has stated that the HW rectifier has capacitor input filter. Otherwise, A will be the correct answer.

Does it have something to do with the Capacitor storing energy in the form of Voltage?

Please explain me.
