Final answer:
OPTION D.
The colligative property that results in a solution having a lower freezing point than the pure solvent is called freezing point depression.
Step-by-step explanation:
The colligative property that means a solution typically has a measurably lower freezing point than a pure solvent alone is known as freezing point depression. When a nonvolatile solute is dissolved in a solvent, it disrupts the solvent's normal freezing process, causing the solution to freeze at a lower temperature compared to the pure solvent. This colligative property is directly proportional to the number of dissolved particles in the solution, which can be expressed using the molality of the solute. It is important to note that this property does not depend on the identity of the solute, but rather the number of solute particles.
