Question: Assertion : An ac generator is based on the phenomenon of self-induction. Reason : In single coil, we consider self-induction only.
Options:
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.
