Assertion : An alternating current does not show any magnetic effect.
Reason : Alternating current does not vary with time.

A

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

B

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

C

If assertion istrue but reason is false.

D

If both assertion and reason are false.
