Answer:
B. Removing heat.
Step-by-step explanation:
This happens through evaporation and condensation, when the water evaporates, it turns into gas when it reaches boiling point, then condensation is when the molecules of the gas cool down; they lose heat and as that happens they also lose energy and slow down, then they move together with other gas molecules which makes them turn into liquid, in conclusion, once the gas molecules cool down and reach the temperature of condensation point, they become liquid.
