Answer:
11. Letter A is a saturated solution
12. Saturated is a solution in which the maximum amount of solvent has been dissolved. Any more solute added will sit as crystals on the bottom of the container.
13. Letter B is a unsaturated solution
14. Unsaturated solution are solution in which the amount of dissolved solute is less than the saturation point of the solvent(at that specific temperature).
15. By heating the solution a saturated solution can be changed into an unsaturated solution. Without adding any solvent it can be changed into an unsaturated solution.
