A.condensation

Condensation is the process by which water vapor in the air is changed into liquid water.

Heat is necessary for evaporation, melting and boiling. The correct option is A.

What is condensation?

Condensation is the transformation of water vapor into liquid. It is the inverse of evaporation, in which water turns into a vapor.

Condensation occurs in one of two ways: the air is either cooled to its dew point or becomes really filled with water vapor that it cannot retain any more water.

Condensation happens when warm air collides with cold surfaces or when your environment is overly humid.

When this moist warm air comes into contact with a cold surface, it quickly cools and releases the water, which condenses into liquid droplets on the cold surface.

In the remaining processes, i.e., evaporation, melting and boiling it is required to heat them up.

Thus, the correct option is A.
