Nitro group being electron withdrawing, deactives the benzene nucleus to such an extent so that it becomes incapable to give Friedel-Crafts reaction. Nitrobenzene because of its unreactivity towards Friedel-Crafts reaction is used as a solvent for this reaction. Nitrobenzene because of its unreactivity towards Friendel -Crafts reaction is used as a solvent for this reaction.
Hence correct option is D.
