NEET Physics (general) Assertion Reason Question
Type: Assertion Reason-assertion-Medium-Class 12
Assertion (A): Doping silicon with a pentavalent element results in the formation of an n-type semiconductor. | Reason (R): A pentavalent dopant contributes extra electrons, increasing the number of charge carriers in the semiconductor.
A
Both A and R are true and R is the correct explanation of A.
B
Both A and R are true but R is not the correct explanation of A.
C
A is true but R is false.
D
A is false.
Correct Answer
Option A
