Solution

The correct option is D ${C H}_{3} - N^{+} \equiv C^{-}$
$C H_{3} N H_{2} + C H C l_{3} + 3 K O H Δ - \to C H_{3} C H_{2} N C + 3 K C l + 3 H_{2} O$
Methylamine on undergoing this reaction, gives methyl carbylamine as above.
When a primary amine is heated with chloroform in the presence of alcoholic potassium hydroxide, then the corresponding isocyanide is formed. Isocyanides are also known as carbylamines, hence this reaction is called as carbylamine reaction.
Isocyanides give a very offensive odour, so this reaction is also used as a test for primary amines.
