Adding more solute to an aqueous solution causes-?

E. None of the Above.

If you add more solute to an aqueous solution, then you have a more concentrated solution, ie, more dissolved solute in the same amount of water. We know nothing about the concentration of solutes in the given solution. A either implies that your original solution was not yet saturated, i,e. not holding as much dissolved solute as possible, and adding more would still not saturate it, or else that it was already supersaturated (see below); B implies that the original solution was already saturated i.e containing the maximum amount of dissolved solute. C is only possible if the solution was formed at a high temperature, with more solute than would be possible at a lower temperature (say room temperature), yet as it cooled the solutes did not precipitate out of the solution (form solid particles). Adding more solute at that time would lead to precipitation of the excess solutes to a concentration expected at that temperature, or even lower as a solute particles continue to precipitate on the solid solute particles.
