    Answer: B. 16

    Explanation:

    The given table:

    x y

    2.5 6.25

    9.4 88.36

    15.6 243.63

    19.5 380.25

    25.8 665.64

    Here, we observed that value of y is the square value of x.

    i.e. y=x^2  [For example 2.5²=6.25, 9.4²=88.36, 15.6²=243.63]

    Put x=4, we get

    y=4^2=16

    Hence, the approximate value of y for x = 4 is 16.

    So, the correct option is B. 16 .
