A solution with a lower solute concentration in comparison to Solution

Hypotonic

Explanation:

When you are comparing solutions with unequal solute concentrations, the solution with a higher solute concentration is a hypertonic, while the one with a lower one is a hypotonic. If they are equal, then they are isotonic.
