Which of the following compounds will undergo racemisation when a solution of $\text{KOH}$ hydrolyses them?

Racemisation occurs during $S_{N}1$ hydrolysis of a chiral alkyl halide.${\text{C}}_6{\text{H}}_5{\text{CHClCH}}_3$ is chiral (the carbon with $Cl$ is bonded to $H$, $Cl$, $C{H}_3$, and $C_6{\text{H}}_5$).It forms a stable benzylic carbocation, favoring $S_{N}1$.Attack of $O{H}^{-}$ on the planar carbocation from either side results in a racemic mixture.
