Assertion : when a pure semiconductor is doped with a trivalen impurity the number of hols becomes more than the number of electrons
Reason Electrons get recombined with the holes as their concentration increases on addition of trivalent impurity so number of holes become more

A

If both asssertion and reason are correct and reason is a correct explanation of the assertion.

B

if both assertion and reason are corect but reason is not the correct explanation of assertion.

C

If assertion is correct but reason is incorrect.

D

If assertion is incorrect but reason is correct
