Answer

Brief Explanations:

Phase diagrams show the states of matter at different temperatures and pressures. Evaporation is liquid - to - gas, condensation is gas - to - liquid, melting is solid - to - liquid, sublimation is solid - to - gas, and freezing is liquid - to - solid. Moving from a higher - temperature point B to a lower - temperature point A on a phase diagram often represents a gas - to - liquid transition which is condensation.

Answer:

b. Condensation
