The correct order of functions for a condenser is Condenses, De-superheat, Subcools. This sequence accurately represents the typical operation of a condenser in an air conditioning system.

In this process:

- Condensing is the initial function where the high-pressure, high-temperature refrigerant gas releases heat and transforms into a high-pressure liquid.

- De-superheating follows condensing and involves removing any remaining superheat in the refrigerant to ensure it is completely condensed.

- Subcooling occurs last, where the temperature of the liquid refrigerant is further reduced below its condensing temperature to improve system efficiency.

The other options are incorrect because they do not reflect the correct sequential order of these functions in a condenser.
