Solution

The correct option is D Alkene
First reaction is as follows:
$C H_{2} = C H_{2} + H B r \to C H_{2} B r - C H_{3}$

In presence of alc. KOH, following reaction takes place:

$C H_{3} - C H_{2} B r + K O H \to C H_{2} = C H_{2} + K B r$

In this process, alc. KOH is used for dehydrohalogenation.

Option D is correct.
