    C

    Explanation:

    Pb + H2O + O2 = > Pb (OH) 2

    Number of oxygen atom on left = 3

    Number of oxygen atom on the right = 2

    To balance number of oxygen

    Change the coefficient of Pb and H2O to two each

    2Pb + 2H2O + O2 = > 2Pb (OH) 2

    The coefficient of Pb and H2O is 2,2
