✓ Answer: D amphoteric
Aluminium oxide (Al2O3) is amphoteric in nature. While most metal oxides are basic, aluminium oxide exhibits amphoteric behavior. This means it can react with both acids and bases: with acids, Al2O3 acts as a base and accepts protons (H+), forming a salt and water; with bases, Al2O3 acts as an acid and donates protons (H+), forming a salt and water.
