Solution

The correct option is A Only $D_{2}$
The potential at the extreme right s lower than that at the extreme left. So, the current flows from left to right.
Now, for $D_{1}$ ,the current enters the p-side and leaves from N-side, while, leaves from the p-side. Thus $D_{2}$ is forward biased while $D_{1}$ is reverse biased
