JEE Main Chemistry question

Which of the following compounds are not arranged in order of decreasing reactivity towards electrophilic substitution?

(A)Fluorobenzene>chlorobenzene>bromobenzene
(B)Phenol>n-propylbenzene>benzoic acid
(C)Chlorotoluene>p-nitrotoluene>2-chloro-4-nitrotoluene
(D)Benzoic acid>phenol>n-propylbenzeneCorrect
