Solution

The correct option is D Has different peak value during positive and negative half cycle
For the given circuit,

For positive half cycle:
in this condition D1 is reverse biased and D2 forward biased.

and wave output diagram is given as

Now for negative half cycle:
in this condion D1 is forward bias and D2 reverse bias.
and also the potential drop in this condition is more than the previous one because of less potential drop at 100 Ω as compared to 150 Ω.
This gives larger potential drop at VAB than previous.
So wave output diagram is given by,

The final output wave:

Hence, option D is correct option.
