To determine the nature of SiO₂, GeO₂, SnO, and PbO, we can classify them based on their chemical properties.

Classification of Oxides

  • SiO₂ (Silicon Dioxide): This oxide is typically considered acidic.
  • GeO₂ (Germanium Dioxide): This oxide is amphoteric, meaning it can act as both an acid and a base.
  • SnO (Tin(II) Oxide): This oxide is also amphoteric.
  • PbO (Lead(II) Oxide): This oxide is generally regarded as basic.

Final Classification

Based on the above classifications, the correct answer is:

A. acidic, amphoteric, amphoteric, basic
