Solution
The correct option is C Nitrobenzene
Nitro group is an electron withdrawing group. It removes electron density from aromatic nucleus.
Thus, the reactivity of nitrobenzene towards electrophilic aromatic substitution reaction is less.
Amino and methyl groups are electron releasing groups. They increase the electron density on benzene ring.
Thus, aniline and toluene are more reactive towards electrophilic aromatic substitution reaction than aniline.
Option B is correct.
