A space explorer on the desert world of Pyra discovers an open basin containing a clear solution of dissolved luminescent mineral salt in water. To harvest the solid glow-salt crystals without needing to condense or recover the water vapor, the explorer leaves the basin under the heat of the planet's twin suns. Which statement best explains how evaporation separates this mixture?

A) Both the water and the dissolved salt vaporize simultaneously at the surface, creating an airborne mineral mist that re-solidifies on the ground.

B) Heating causes a chemical reaction between the water and salt, destroying the salt particles so that only pure liquid remains.

C) The volatile liquid solvent gains thermal energy and transitions into vapor, leaving the non-volatile solid solute behind as dry crystals.

D) The dissolved salt floats to the surface and boils away before the water because dissolved solids always have lower boiling points than liquids.
