The reaction of hydrolyzation of esters will be used to obtain carboxylic acids or salts and also alcohols, and it is usually performed using the ester, water, dilute acid or dilute alkali. The reaction using pure water is extremely slow, so it will be rarely used, therefore the reaction will be catalyzed by a dilute acid, good examples of dilute acids used in this reaction are hydrochloric acid and sulfuric acid.

The best option given in the question will be H2SO4, which in this reaction will be the dilute acid
