Given below are two statements : One is labelled as Assertion A and the other is labelled as Reason R. Assertion A : A n-p-n transistor permits more current than a p-n-p transistor. Reason R : Electrons have greater mobility as a charge carrier. Choose the correct answer from the options given below: (1) Both A and R are true, and R is correct explanation of A. (2) Both A and R are true but R is NOT the correct explanation of A. (3) A is true but R is false. (4) A is false but R is true.

1. Both A and R are true, and R is correct explanation of A.
2. Both A and R are true but R is NOT the correct explanation of A.
3. A is true but R is false.
4. A is false but R is true.

Correct answer: Both A and R are true, and R is correct explanation of A.

Solution

The assertion is correct because n-p-n transistors do allow for higher current flow due to the greater mobility of electrons compared to holes in p-n-p transistors, making the reason a valid explanation for the assertion.
