Explanation:

Colligative properties depend on the number of solute particles in a solution. Boiling - point elevation, freezing - point (melting - point) depression, osmotic pressure, and vapor - pressure lowering are colligative properties. Enthalpy is a thermodynamic property that is not related to the number of solute particles in the same way as colligative properties. It is a measure of the total heat content of a system.

Answer:

C. Enthalpy
