Which of the Following Statements About How Acid Catalyzes the Hydrolysis

Which of the following statements about how acid catalyzes the hydrolysis of esters is correct?

A) The acid catalyst increases the rate of formation of the tetrahedral intermediate by protonating the carbonyl and thereby increasing the reactivity of the carbonyl group.
B) The acid catalyst increases the rate of the reaction by changing the basicity of the group eliminated when the tetrahedral intermediate collapses.
C) The acid catalyst protonates the water,the nucleophile in the reaction,and thereby makes it a stronger nucloephile.
D) both A and B
E) all of the above
