Solution

The correct option is A reaction with $C H C l_{3}$ and alc. KOH
The presence of primary amines can be confirmed in laboratory by carbylamine reaction.

Carbylamine reaction is given by primary amines. It is not given by secondary or tertiary amines.

In Hoffmann's carbylamine test (also known as Isocyanide test), aliphatic or aromatic primary amine is heated with chloroform in presence of alcoholic potassium hydroxide to give foul smeling alkyl/aryl isocyanide or carbylamine.

$C_{6} H_{5} - N H_{2} + C H C l_{3} + 3 K O H h e a t - - \to C_{6} H_{5} - N C + 3 K C l + 3 H_{2} O$

Option B is correct.
