Solution

The correct option is C $Z n O$
In chemistry, an amphoteric compound is a molecule or ion that can react both as an acid as well as a base. Many metals (such as copper, zinc, tin, lead, aluminium, and beryllium) form amphoteric oxides or hydroxides. So, $Z n O$ dissolves in sulphuric acid as well as in sodium hydroxide.
