Solution

The correct option is D $C H_{3} C H_{2} N H_{2}$
$C H_{3} C H_{2} C O O H (A) S O C l_{2} - ------ \to - S O_{2}, - H C l C H_{3} C H_{2} C O C l (B) N H_{3} - -- \to - H C l C H_{3} C H_{2} C O N H_{2} (C) 4 K O H + B r_{2} \to (D) C H_{3} C H_{2} N H_{2} e t h y l a m i n e$

The reaction is Hofmann bromamide reaction.

Option D is correct.
