A. If both Assertion \& Reason are True \& the Reason is a correct explanation of the Assertion.
\( \mathrm{P} \)
B. If both Assertion \& Reason are True but Reason is not a
W correct explanation of the Assertion.
C. If Assertion is True but the Reason is False.
D. If both Assertion \& Reason are False.
Assertion : P-type semiconductor has high density of holes in valence band while N-type semiconductor has high density of electrons in
- conduction band.
Reason : In N-type semiconductor, as the density of donar atoms \( \mathrm{N}_{\mathrm{D}} \) is increased, the fermi energy level shifts towards the valence band.
