What is a solution? On which factors is a solution said to be diluted,concentrated,or saturated?

(N/A) solution is a homogeneous mixture of two or more substances.
$A$ solution is classified as diluted,concentrated,or saturated based on the amount of solute dissolved in a given amount of solvent at a specific temperature.
$1$. Diluted solution: $A$ solution containing a relatively small amount of solute in a given volume of solvent.
$2$. Concentrated solution: $A$ solution containing a relatively large amount of solute in a given volume of solvent.
$3$. Saturated solution: $A$ solution in which no more solute can be dissolved at a given temperature.
