What type of solution contains the maximum amount of solute dissolved at a given temperature?

A saturated solution is defined as a solution that has reached its maximum capacity for solute at a specific temperature. In this case, the solute can no longer dissolve in the solvent, meaning any additional solute added will remain undissolved. This characteristic of saturated solutions is crucial for understanding solubility concepts in chemistry.

In contrast, a concentrated solution contains a relatively large amount of solute compared to the solvent but does not necessarily imply that it has reached the maximum solubility limit at that temperature. A dilute solution has a small amount of solute compared to the solvent, and an unsaturated solution can still dissolve more solute, indicating that it has not reached its saturation point. This clear distinction illustrates why a saturated solution is the correct choice for this question.
