We can find out concentration of solution by dividing number of moles by volume.

Most concentrated solution is the solution with highest number of moles in a unit volume

Concentration = number of moles / volume

1. 0.1 mol / 0.4 L = 0.25 mol/L

2. 0.2 mol / 0.3 L = 0.67 mol/L

3. 0.3 mol / 0.2 L = 1.5 mol/L

4. 0.4 mol / 0.1 L = 4.0 mol/L

From the given solutions most concentrated solution is 4th solution. In this the highest amount of solute dissolved in a unit volume is 4.0 mol. Therefore this is the most concentrated solution.
