Concept:Evaporation is the only process that can take place at any temperature because liquid molecules at the surface can escape into gas even below the boiling point.Explanation:Boiling requires the liquid to reach its boiling point.Melting requires a solid to reach its melting point.Sublimation requires specific temperature and pressure conditions.Evaporation happens continuously from the surface of a liquid at all temperatures, as long as the liquid is present.Answer:B. Evaporation
