    would it be C evaporating alcohol?

    no, since after the evaporation, alcohol has more energy than before the same evaporation

    we have to search for a transformation in which the amount Q of heat transferred is negative

    please we have to say this: if we consider as thermodynamic system the water only, the answer is C. Nevertheless, we have to keep in mind that in all natural phenomena entropy can only increase

    ohhh but because that is not the case, and that it has to increase, it must be freezing water? :O

    yes! the answer of @JFraser is correct! we have to be careful what we mean with thermodinamic system
