The acidic, basic and amphoteric oxides, res-
pectively, are :

We know that 

Non-metal oxides are acidic in nature, and they dissolve in water to form acids.

i.e. ${\mathrm{N}}_2{\mathrm{O}}_3$.

Alkali metal oxides are basic in nature, they combine with water to form bases which are usually called metal hydroxides i.e., ${\mathrm{Li}}_2\mathrm{O}$.

An oxide known as an amphoteric oxide can function as either an acid or a base in a process that yields salt and water.

${\mathrm{Al}}_2{\mathrm{O}}_3$ is amphoteric oxide.

Hence, option(c) is the answer.
