    The correct answer is :D) Aluminium oxide

    Explanation:
    • Amphoteric oxides are those that can react with both acids and bases. Aluminium oxide (Al₂O₃) is an amphoteric oxide because it can react with both acidic and basicsubstances to form salts and water.
    • For example, it reacts with acids like HCl to form aluminium chloride and with bases like NaOH to form sodium aluminate.
    Information Booster:
    • Amphoteric Oxides: Oxides of elements like Zinc (ZnO), and Lead (PbO) are amphoteric.

    • Basic Oxides: Oxides like Calcium oxide (CaO) and Sodium oxide (Na₂O) are basic.

    • Acidic Oxides: Oxides like Sulfur dioxide (SO₂) and Carbon dioxide (CO₂) are acidic.
    Additional Information:

    • Sodium peroxide: A compound formed by sodium and oxygen, often used as a bleaching agent and in oxygen generation.

    • Calcium oxide: A white solid, also known as quicklime, formed by heating calcium carbonate.
