Correct answer
A(A)>(B)>(C)>(D)

Step-by-step explanation

+M  group attached with carbonyl bond will decrease reactivity of acid derivative towards hydrolysis. For halogen -I dominate over +M therefore, acid chloride is most reactive. As extent of +M effect increases, reactivity decreases. Overall, order of reactivity is:
