    Answer : Option D

    Explanation :

    The refrigerant vaporizes from the heat it absorbs heat in the evaporator. Flow control device (expansion valve): This controls the flow of the liquid refrigerant into the evaporator. Control devices usually are thermostatic, meaning that they are responsive to the temperature of the refrigerant.
