Assertion (A): The conductivity of p type semiconductor is higher than that of intrinsic semiconductor. Reason (R): The addition of donor impurity creates additional energy levels below conduction band.

Assertion (A): The conductivity of p type semiconductor is higher than that of intrinsic semiconductor.

Reason (R): The addition of donor impurity creates additional energy levels below conduction band.

[A].	Both A and R are true and R is correct explanation of A
[B].	Both A and R are true but R is not a correct explanation of A
[C].	A is true but R is false
[D].	A is false but R is true

Answer: Option B

Explanation:

A refers to type semiconductor while R refers to n type semiconductor. Both A and R are correct but independent.
