Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
The reason is the correct explanation for the assertion.
Correct explanation is as follows,
Consider the figure the ABCD,
rate of change of flux = $B \times l e n g h t A C \times v$
emf = $B l v$
