The cut in voltage of both Zener diode $${D_z}$$ and diode $$D$$ shown in Figure is $$0.7$$ $$V,$$ while break down voltage of the zener is $$3.3$$ $$V$$ and reverse breakdown voltage of $$D$$ is $$50$$ $$V.$$ the other parameters can be assumed to be the same as those of an ideal diode. The values of the peak output voltage ($${V_0}$$) are
A
$$3.3$$ $$V$$ in the positive half cycle and $$1.4$$ $$V$$ in the negative half cycle.
B
$$4$$ $$V$$ in the positive half cycle and 5 V in the negative half cycle.
C
$$3.3$$ $$V$$ in both positive and negative half cycle.
D
$$4$$ $$V$$ in both positive and negative half cycle.
