Solution

The correct option is B Acid and base
In (A), ZnO is reacting with sodium oxide which is Basic in nature and forming a salt So it means here, ZnO is acting as an Acid.
In (B), ZnO is reacting with Carbon dioxide which is Acidic in nature and forming a salt So it means here, ZnO is acting as an Base.
Also, Zno is a famous amphoteric oxide, which can act as acid in presence of base and vice versa.
So, (D) option is correct.
