1.

In figure, V_(o) is the potential barrier across a p-n junction, when no battery is connected across the junction.

Answer»

1 and3 both correspond to forward bias of junction.
3 corresponds to forward bias of junction and 1 corresponds to reverse bias of junction.
1 corresponds to forward bias and 3 corresponds to reverse bias of junction.
3 and1 both correspond to reverse bias of junction.

Solution :3 corresponds to forward bias of junction and 1 corresponds to reverse bias of junction.
When p-n junction is forward BIASED, magnitude of barrier potential (i.e. HEIGHT of potential barrier) becomes smaller than `V_(0)`, which is seen in graph 3.
When p-n junction is reverse biased, magnitude of barrier potential becomes greater than `V_(0)`, which is seen in graph 1.
Thus, option (B) is CORRECT.
