Final answer:

The freezing point depression of a solution is affected by the solvent's freezing point, the solution's molality, the solute's Vant Hoff factor, and the solvent-specific molal freezing point depression constant. So the answer is A, B, C, E, and G directly influence freezing point depression, while factors D and F are not directly related to freezing point depression.

Step-by-step explanation:

The factors that affect the freezing point depression of a solution are the freezing point of the solvent, the molality of the solution, the Vant Hoff factor of the solute, and the molal freezing point depression constant specific to the solvent.

The freezing point of the solute, the molarity of the solution, and the Vant Hoff factor of the solvent do not have a direct effect on the freezing point depression. The depression in the freezing point is a colligative property, dependent on the number of solute particles in the solution, rather than the chemical identity of the solute itself.

The relationship is defined by the equation ΔTf = Kf * m, where ΔTf is the depression in the freezing point, Kf is the molal freezing point depression constant, and m is the molality of the solute in the solution.
