Solution

The correct option is B $0$
${C H}_{3} C O O C_{2} H_{5} + H_{2} O ⇌ {C H}_{3} C O O H + C_{2} H_{5} O H$

If the above reaction is carried out with a large excess of ester, the rate of reaction does not depend upon the concentration of both reactants. Due to which, the reaction becomes of zero order.
