    Answer:

    D

    Explanation:

    In a fixed pulley system, there is load, carried bi the strings and also there is effort which is the number of the turns of strings or number of the wheels in the pulley system

    Since

    mechanical \: advantage = \frac{load}{effort}

    There is M.A in the fixed pulley system

    But in other objectives, there is load but they lack effort, hence they cannot give mechanical advantage
