Is the Food Compartment in a Refrigerator Cooled by Evaporation

Is the food compartment in a refrigerator cooled by evaporation or condensation of the refrigerating coolant?

A) The food compartment of a refrigerator is cooled by evaporation of the refrigerating fluid because vaporization is a cooling process.
B) The food compartment of a refrigerator is cooled by condensation of the refrigerating fluid because condensation is a cooling process.
C) Both evaporation and condensation of the refrigerating coolant cause the food compartment to cool.
D) It is neither the evaporation nor condensation of the refrigerating coolant that causes the food compartment to cool. Cooling is a matter of simple heat exchange via the refrigerator's motor.
