Solution

The correct option is A
Answer : (a)
Hoffmann bromamide reaction is used for the conversion of a primary amide to a primary amine with one less carbon atom. This is accomplished by heating the primary amide with a mixture of a halogen (chlorine or bromine), a strong base, and water.
Hoffmann bromamide degradation of benzamide:

Hence, product A is aniline.

Aniline is a primary amine (contains -NH2 group).
When it is treated with chloroform under alkaline conditions, it results in the formation of a bad smelling compound, known by the name isonitrile or carbylamine.
This reaction is known as carbylamine reaction.
