Solution

The correct option is A Both Assertion and Reason are correct and the Reason is the correct explanation of the Assertion
In acidic medium $H^{+}$ acts as catalyst while alkaline medium ${O H}^{-}$ acts as reactant by forming intermediate. Hence hydrolysis of ethyl acetate in presence of acid is first order and Alkaline medium is second order.
