Answer:
In electrophilic substituition mechanisam, favours the group for electon donor and reduce the rate of the electron withdrawing group.
So electron withdrawing group can show their impact by two means.
1)Inductive means: So by indcutive impact of the group they can attract the more elecetron like halide
2) resonance means: after electron withdrawing group, they will form the stable structure because of resonance like Nitro group
In case of CF3 have only inductive impact to withdarw the electron , R-C=O and R-C-O- is not that much inductive and can stabilize by the resonance
Based on all Nitro group having the both inductive and resonance impact because of it withdraws the electron and also with resonance, it can stabilize the reaction
so correct answer is first option I(Nitro Benzene)

Can someone explain how I am supposed to know which is least
reactive compared to most reactive? I know that the benzene with
the NO2 group on it is least reactive because it's an EWG (electron
withdrawing group) so a deactivator but how do I compare the
others? Thanks!!!
