Solution

The correct option is C
$H O - Z ⊖ n C l_{2}$

Zinc chloride is a Lewis acid and coordinates with the alcoholic group.
$R - . . O . . + Z n C l_{2} \to R - + O H - Z ⊖ n C l_{2} \to R^{+} + H O - Z ⊖ n C l_{2}$
$R^{+} + C l^{-} (f r o m H C l) \to R C l + H^{+}$
$H^{+} + H O^{-} Z n C l_{2} \to H_{2} O + Z n C l_{2}$
