A solution that contains a large amount of solute is most likely to be
concentrated
A solution that contains a large amount of solute in a given amount of the solvent is called a concentrated solution.
Let's suppose 50 g is the maximum amount of sugar that can be dissolved in 100 mL of solution with the solvent as water. When 5 g of sugar is dissolved, it forms a dilute solution, i.e., it has a low concentration. When 40 g of sugar is dissolved, it makes a concentrated solution as the amount of the solute dissolved is higher.
