Which of the following amines give both a positive carbylamine test and an orange-red dye when diazotised with $\mathrm{NaNO}{}_2/\mathrm{HCl}$ at $273\mathrm{K}$ and then coupled with alkaline 2-naphthol?

Both tests are given by primary amines, but the dye test needs a stable aryl diazonium salt, which comes only from primary aromatic amines. Aniline and 4-methylaniline satisfy both. Benzylamine is a primary aliphatic amine (carbylamine positive) but its diazonium salt is unstable and gives an alcohol instead. N-Methylaniline is secondary and is carbylamine negative.
