It's B only since it is not stated as to what is the position or orientation of the diode with respect to the source, so what if during the negative half cycle the diode is forward biased then the capacitor will not discharge hence D is wrong. So, the only feasible answer would be the time when the diode is not conducting.

I think option B is as same as D, so the Answer is B or D.

But the voltage regulator may produce a negative DC voltage (by reversing the diode) thus conducting only at negative so technically option D is only correct for positive DC output. The safest answer will be B in reference to the diode itself.

My question is that, a diode does not conduct during the negative half cycle, as it is reversed biased. So option D is also correct, logically. Am I right?

In which part the diodes will be nonconducting. And how the capacitor will get discharged.
