    The correct option is A

    Step-by-step explanation:

    The expression is

    2y3 - 27 + 5y2 + (25 / 5)

    Substitute the value of y=2 in the expression:

    =2 (2) ³-27+5 (2) ² + (25/5)

    We know that 2³ means multiply 2 three times

    2³ = 2*2*2=8

    Likewise 2²=2*2=4

    =2 (8) - 27+5 (4) + (25/5)

    =16-27+20+25/5

    Now take the L. C. M which is 5

    =80-135+100+25/5

    Solve the values in the numerator:

    =70/5

    =14

    Thus the correct option is A ...
