Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Rate expression for the given reaction suggest that order of reaction with respect to C is zero. Hence it does not depend upon the concentration of C. Hence assertion and reason both are true and reason is the correct explanation of assertion.
