Chlorobenzene is heated with aqueous NaOH at about $623 K$ and about $300$ atm (Dow process) and the product mixture is then acidified. The main organic product is

Abenzoic acid
Bcyclohexanol
Cphenol
Dbenzene

Answer: C

Under these forcing conditions hydroxide replaces chlorine of the unactivated aryl chloride, giving sodium phenoxide. Acidification protonates the phenoxide. The ring is not reduced or oxidised, so the product is phenol.
