    Answer is B) 13L.

    Explanation:

    We can calculate the number of liters of cleaning solution required to clean up a surface with the given area by simple method of proportion.

    If 25m^2 area requires 5L of cleaning solution,

    then let x be the number of liters required for cleaning a 65m^2 area.

    We can write it as:

    25 / 65 = 5 / x

    x = (5 x 65) / 25 = 325/25 = 13

    So, 13 litres of cleaning solution is required to clean a surface with 65m^2 area.
