    option (c) 9 mg

    Step-by-step explanation:

    Data provided:

    Amount of copper that must be contained in the feed = 4 mg per kilogram

    Amount of dry matter being consumed by the pig = 5 pounds

    Now,

    1 pound = 0.45 kilograms

    thus,

    5 pounds = 0.45 * 5 = 2.25 kilograms

    thus,

    amount of dry matter being consumed by the pig = 2.25 kg

    therefore,

    the amount of copper consumed = 4 mg per kilogram * 2.25 kg

    or

    the amount of copper consumed = 9 mg

    Hence,

    the correct answer is option (c) 9 mg
