    C) \[Al>Mg>Na>Si\]

    D) \[Si>Al>Na>Mg\]

    Correct Answer: A

    Solution :

    [a] The metallic character of the elements is highest at the extremely left (low ionisation energies) and then decreases across the period from left to right (ionisation energies increases across the period).
