(D) $1.$ $CHCl_3 / Alc. KOH$ (Carbylamine test): Only $1^o$ amines give a foul-smelling isocyanide,while $2^o$ amines do not.$2.$ $NaNO_2 / HCl$: $1^o$ aliphatic amines form unstable diazonium salts that evolve $N_2$ gas,whereas $2^o$ amines form $N$-nitrosoamines (yellow oily liquids).$3.$ $PhSO_2Cl$ (Hinsberg reagent) then $NaOH$: $1^o$ amines form a sulfonamide soluble in $NaOH$,while $2^o$ amines form a sulfonamide insoluble in $NaOH$.Since all three reagents can distinguish between $1^o$ and $2^o$ amines,the correct answer is $D$.
