B Correct answer
Explanation

Condensation is the process where water vapour (gas) cools down and changes state into liquid water - this is what you see as water droplets on cold surfaces or clouds forming. Evaporation is the reverse (liquid to gas), crystallization is formation of solid crystals from solution, and sublimation is solid directly becoming gas without passing through liquid state.
