Final answer:

Aqueous FeI₃ will have the lowest freezing point.

Step-by-step explanation:

When a solute is dissolved in a solvent, the freezing point of the solution decreases. This is known as freezing point depression. The greater the concentration of particles in the solution, the greater the freezing point depression. In this case, the solution with the lowest freezing point would be the one with the highest concentration of solute particles. Aqueous FeI₃ has the highest concentration of solute particles among the given options, so it will have the lowest freezing point.
