Consider the oxides of group 14 elements
$$\mathrm{SiO}_2, \mathrm{GeO}_2, \mathrm{SnO}_2, \mathrm{PbO}_2, \mathrm{CO}$$ and $$\mathrm{GeO}$$. The amphoteric oxides are
$$\mathrm{SnO}_2, \mathrm{CO}$$
$$\mathrm{SiO}_2, \mathrm{GeO}_2$$
$$\mathrm{SnO}_2, \mathrm{PbO}_2$$
$$\mathrm{GeO}, \mathrm{GeO}_2$$
Explanation
SnO$$_2$$ and PbO$$_2$$ are amphoteric.
