Solution :-

The carbylamine test is a chemical test used to detect primary amines (only aliphatic or aromatic $1^{\circ }$ amine)

$\mathrm{R}-{\mathrm{NH}}_2+{\mathrm{CHCl}}_3+3\mathrm{KOH}\to \mathrm{R}-\mathrm{NC}$ (isocyanide) $+3\mathrm{KCl}+3{\mathrm{H}}_2\mathrm{O}$ Option 1,2 and 4 are primary amines, so they give a positive isocyanide test.

Final answer :- A,B and D
