(c)
Aliphatic and aromatic primary amines on warming with $CHCI_{3}$ and alcoholic KOH form isocyanide or carbylamine which has very unpleasant smell. This reaction is known as carbylamine reaction.
Since p-toluidine contains an aromatic primary amine group, it undergoes similar reaction and give 4-methyl phenyl isocyanide.
