Text Solution

Verified by Experts
The correct answer is:
D

In a p-type semiconductor, the material is doped with trivalent impurities (like Boron in Silicon). These impurities create acceptor levels that can accept electrons from the valence band, creating holes as majority carriers.

The acceptor level lies close to the valence band to make it easy for electrons from the valence band to jump into the acceptor level.
