    C) 0.45

    Step-by-step explanation:

    Given that a population mean is 0.45, standard deviation is 0.001 and margin of error stands at 0.5% we have the following

    0.45 + 0.001 = 0.451

    Population mean with standard deviation is 0.451.

    0.451 * 0.5% = 0.448745

    We now reduce the number to two decimals and get the final marigin of error

    0.45 as result
