(C) $SbCl_5$ acts as a Lewis acid and abstracts the chloride ion from $(-)-1-$chloro$-1-$phenylethane to form a stable benzylic carbocation intermediate: $Ph-CH(Cl)-CH_3 + SbCl_5 \to [Ph-CH^+-CH_3] + SbCl_6^-$. Since the carbocation is planar,the nucleophilic attack by $Cl^-$ can occur from either side,leading to the formation of a racemic mixture.
