    The turn and voltage ratio of a transformer can be simply expressed by the equation:

    Ns/Np = Vs/Vp; where N is the number of turns and V is the voltage.

    Plugging in the given values, we have:

    25 turns / 100 turns = Vs / 40 volts

    Vs = 40 volts (25 turns/100 turns)

    Vs = 10 volts

    The answer is D.
