    A Ductility Correct Answer Incorrect Answer
    B Galvanisation Correct Answer Incorrect Answer
    C Anodising Correct Answer Incorrect Answer
    D Corrosion Correct Answer Incorrect Answer

    Solution

    Anodising is an electrochemical process that thickens and toughens the naturally occurring protective oxide on aluminum. This process enhances corrosion resistance and allows dyeing (coloring), improved adhesion of paints and glues, and electrical insulation.
