Question
Assertion

The resistivity of a semi-conductor increases with temperature.

Reason

The atoms of semi-conductor vibrate with larger amplitude at higher temperatures thereby increasing its resistivity.

A

Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

B

Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion

C

Assertion is correct but Reason is incorrect

D

Both Assertion and Reason are incorrect
