The correct answer is (b) Saturated
Explanation: Saturated solutions are those which contain maximum amount of solute that is soluble and cannot be further dissolved. Dilute solutions have a very low concentration of the salt. Unsaturated solutions have concentration of solute lesser than its solubility. Supersaturated solutions contain more amount of solute than how much is soluble in the solvent. In other words, adding more solute to a saturated solution results in a supersaturated solution.
