B. 110V
C. 0V
D. 220 \sqrt{2}V

As p-n junction diode will conduct during positive half cycle only during the negative half cycle diode is reverse biases. during this diode will not give any output so potential difference across capacitor C-peak voltage of the given AC voltage

 V_{0}=V_{nms}\sqrt{2}=220 \sqrt{2}V
