Aromatic nitriles (ArCN) are not prepared by reaction

Q: Aromatic nitriles $(ArCN)$ are not prepared by reaction

a (a) Halogen have $-I$ and $+M$ effect by which its electron delocalized in benzene ring by resonance & due to its $-I$ effect its bonded with benzene ring and cannot be substitute by $C{N^ - }$ & show the inertness against $KCN$ while other option gives Aromatic nitrile $ArN_2^ + + CuCN \to ArCN + {N_2} + C{u^ + }$ $ArCON{H_2}\mathop {\xrightarrow{{{P_2}{O_5}}}}\limits_{ - {H_2}O} ArCN$ $ArCON{H_2} + SOC{l_2} \to ArCN + S{O_2} + 2HCl$
