Assertion (A) : Group-`15`-doped crystal of `Si` are called `n`-type semiconductors.
Reason (R ) : Neutrons are responsible for the semi-conducting properties.

Options

A. If both `(A)` and `(R)` are correct, and `(R)` is the correct explanation of `(A)`
B. If both `(A)` and `(R)` are correct, but `(R)` is not the correct explanation of `(A)`
C. If `(A)` is correct, but `(R)` is incorrect.
D. If both `(A)` is incorrect, but `(R)` is correct.

Answer

C

Explanation

(A) is correct.
Correct (R): `n` stands for negative so electrons are responsible for semiconducting properties.
