Given below are two statements : One is labelled as Assertion A and the other is labelled as Reason R . Assertion 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.

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