Which of the following compounds are not arranged in order of decreasing reactivity towards electrophilic substitution
A. Flurobenzene `gt` chlorobenzene `gt` bromobenzene
B. Phenol `gt n`-propyl benzene `gt` benzoic acid
C. Chlorotoluene `gt` para-nitrotolunene `gt 2`-chloro-`4` nitrotouene
D. Benzoic acid `gt` phenol `gt n`-propyl benzene
