A
Elimination
B
Addition
✓
Substitution
D
Dehydrohalogenation

✓

Answer

Correct option: C.

Substitution

c
Alkyl halides on alkaline hydrolysis get converted into alcohols. This takes place by a nucleophilic substitution reaction where the $- X$ atom is substituted by a nucleophile i.e-$OH$ group.

The primary alkyl halides undergo nucleophilic substitution reaction by $S _{ N } 2$ mechanism, while tertiary alkyl halides follow $S _{ N } 1$ mechanism.

$R - X + KOH \rightarrow R - OH + KX$
