Option B is correct it is twice the secondary Voltage.

What if the question was.
The peak inverse voltage across a nonconducting diode in a unfiltered bridge rectifier equals approximately?

Ans C is right ,
# piv for half- wave rectifier is Vm
# full-wave rectifier is 2Vm
# bridge rectifier is Vm
Because which are the entire secondary voltage appears across the non-conducting diodes
As far question option C is correct.
# piv for half- wave rectifier is Vm
# full-wave rectifier is 2Vm
# bridge rectifier is Vm
Because which are the entire secondary voltage appears across the non-conducting diodes
As far question option C is correct.

No the answer is right, for half wave rectifier, max voltage appearing across trnsfrmr secondary, for fulll wave it is 2*tnsfrmer secndry. For bridge it is max trnsfermer secndry voltage.

Actually the answer is B. Because by using bridge configuration the PIV is increased twice.

I think the answer is B.
The diode has to withstand another peak voltage during the negative half cycle since the bridge rectifier is a full wave rectifier.
