Answer: (B)

Verified step by step guidance

1. Understand the phase changes between states of matter: solid, liquid, and gas.
2. Identify that the process of changing from a gas or vapor to a liquid is the reverse of evaporation.
3. Recall that evaporation is the change from liquid to gas, so the reverse process is called condensation.
4. Note that sublimation is the direct change from solid to gas, and melting is the change from solid to liquid, so neither fits the description.
5. Therefore, the term that describes the process of changing from a gas or vapor to a liquid is condensation.
