Assertion : Bending a wire does not effect electrical resistance.
Reason : The resistance of wire is proportional to the resistivity of material.

A

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

B

If both assertion and reason are true but reason is not the correct explanation of the assertion

C

If assertion is true but reason is false

D

If the assertion and reason both are false.

Text Solution
