In the figure $V_0$ is the potential barrier across a p-n junction, when no battery is connected across the junction. Effective barrier potential heights A and C are found when p-n junction is baised. Choose the correct option.

A and C both correspond to forward bias of junction C corresponds to forward bias and A to Reverse bias. A corresponds to forward bias and C to reverse bias C and A both correspond to reverse bias

C corresponds to forward bias and A to Reverse bias.

The correct answer is Option (2) - C corresponds to forward bias and A to Reverse bias.
