Correct answer
D

Step-by-step explanation
Assuming AC start with positive voltage, when +ve voltage is across input then the capacitor start charging, trying to reach saturation value, till there is +ve voltage across input, when ve voltage of AC appears across input, the capacitor starts discharging till there is ve voltage across input and this process of charging and discharging keeps on going alternatively.
