Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Hydrolysis of ethyl acetate in the presence of acid is a reaction of pseudo first order whereas in the presence of alkali, it is a reaction of second order.
Acid acts as a catalyst only whereas alkali act as one of the reactants.
Hence, both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
