    Option D

    Explanation:

    The total sales (in thousands) of all the seven years for various batteries
    are : a t.
    For 4AH = 75 + 90 + 96 + 105 + 90 + 105 + 115 = 676
    For 7AH = 144 + 126 + 114 + 90 + 75 + 60 + 85 = 694
    For 32AH = 114 + 102 + 75 + 150 + 135 + 165 + 160 = 901
    For 35 AH = 102 + 84 + 105 + 90 + 75 + 45 + 100 = 601
    For 55 AH = 108 + 126 + 135 + 75 + 90 + 120 + 145 = 799.
    Clearly, sales are maximum in case of 32AH batteries.
