The correct option is
D amphoteric
The
PbO2 behaves as acidic and basic property so it is called as amphoteric.
When PbO2 dissolved in a strong base PbOH6 is obtained so it is an acidic property.
when PbO2 dissolved in HCl,PbCl6 is formed so it is a basic property.
Thus PbO2 behaves as amphoteric in nature.
