Solution

The correct option is A An elimination reaction
Alkyl halide gives alkene on Dehydrohalogenation, reaction takes place in presence of alc. $K O H .$ This reaction is called an elimination reaction.
$C H_{3} C H_{2} B r + A l c . K O H \to C H_{2} = C H_{2} + K B r + H_{2} O$

There are two types of elimination reactions.
(a) $E_{1} \to$ Unimolecular elimination
(b) $E_{2} \to$ Bimolecular elimination
