Solution
The correct option is A oxides are amphoteric Amphoteric oxides are compounds that have the properties of both acids and bases. They have acidic property against bases and basic properties against acids.
ZnO, PbO, SnO are examples of amphoteric oxides.
Basic oxides are oxygen-rich compounds of metals. The metals have basic properties as well as their oxides.
Cao, MgO, MnO, FeO, CuO are some examples of basic oxide.
