Reason ( \(R\) ) : Donor energy level is just above the valence band in a semiconductor.

a

Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).

b

Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).
