The specific reactant structure and the structures of the options are missing from the provided text. Therefore, a detailed explanation cannot be provided. Generally, primary aromatic amines react with $NaNO_2/HCl$ (which generates $HNO_2$) at low temperatures ($0-5^\circ\text{C}$) to form diazonium salts, while primary aliphatic amines give alcohols with the evolution of nitrogen gas.
