    Answer : Option D

    Explanation :

    It is very important that the refrigerant has a low boiling point, that is it should have the ability to turn into gas easily when it absorbs heat.
    If it has a high boiling point, the compressor will have to create too much of a vacuum in order to lower the pressure to make vaporization happen.
