Answer: Saturated
A solution that contains the maximum amount of solute that is soluble at a given temperature is said to be saturated.
Explanation:
A Saturated solution is one that contains as much (i.e maximum) solute as it can dissolve at that temperature in the presence of undissolved solute particles.
For instance: if a given volume of water can only dissolve a certain amount of salt in it at room temperature, then, more salt added will not dissolve.
Thus, making the solution saturated.
