Assertion (A): Two transistors one n-p-n and the other p-n-p are identical in all respects (doping, construction, shape, size). The n-p-n transistor will have better frequency response.
Reason (R): The electron mobility is higher than hole mobility.
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
