Text Solution

Verified by Experts
The correct answer is:
B

When the p-end of the p-n junction is connected to the negative terminal and n-end to the +ve terminal of a battery, the p-n junction becomes reverse biased. Its resistance becomes very large. Thus it behaves like a capacitor whose two conducting plates are separated by an insulator.
