    The correct option is B.

    Step-by-step explanation:

    Solution:

    The shortest on map is 7cm

    The longest on map is 14 cm

    The shortest in real life is 120 km

    Let the longest in real life is x km

    So,

    The ratio is:

    7/120 = 14/x

    x = 120 * (14) / 7

    x=1,680/7

    x = 240 km

    The longest in real-life is 240 km

    Thus the correct option is B ...
