John is doing an experiment to determine the solubility of sodium chloride (NaCl) in pure water (H2O). He adds more and more salt into the water, and after a while, he reaches the saturation point, and no more salt can be dissolved.

Which correctly describes John’s solution?

Only the solvation process has completely stopped.
Only the crystallization process has completely stopped.
Both solvation and crystallization continue to occur.
Both solvation and crystallization have completely stopped.
