Zinc sulphide reacts with oxygen and gives two oxides, X and Y. If nature of X is acidic, the nature of Y is
Show Hint
Amphoteric oxides react with both acids and bases. ZnO is a classic example, and is often formed alongside acidic SO$_2$ when roasting ZnS.

The Correct Option is D
Solution and Explanation
When zinc sulphide (ZnS) is roasted in oxygen, it produces sulfur dioxide (SO$_2$, acidic oxide) and zinc oxide (ZnO, amphoteric oxide). So, if one of the products (X) is acidic (SO$_2$), then the other product (Y) must be amphoteric (ZnO).
