Solution

The correct option is A Water
When metal oxides or metal hydroxides react with acid, they form salt and water.
For example:
Zinc oxide reacts with hydrochloric acid to give zinc chloride and water. The reaction takes place as follows:

$ZnO (aq) + 2 HCl (aq) \to {ZnCl}_{2} (aq) + H_{2} O (l)$
