Assertion (A): Doping silicon with a pentavalent element results in an n-type semiconductor. | Reason (R): Pentavalent elements have five valence electrons, which provide extra electrons as charge carriers.
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
