Q1:

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

ANS:B - Both A and R are true but R is not a correct explanation of A

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