    B) n=5

    Explanation:

    We call the initial value Xo. We start to double this initial value

    X1=2*Xo n=1

    We double again:

    X2=2*X1=2 * (2Xo) n=2

    X2=2*X1=2^2*Xo n=2

    In general:

    Xn = (2^n) * Xo

    If we want to reach a value 32 times its initial value:

    2^n=32

    then: n=5

    2^5=2*2*2*2*2=32
