In terms of physical chemistry, collagative property is basically something that depends on the number of molecules that are there in a given space. The right answer to the options provided in the above question is elevation of boiling point, since this is the only solution that comprises of collagative properties. Some of the other solutions are osmotic pressure, freezing point depression, and vapor pressure lowering.
These properties are the ones that generally depend on the number of other solute particles rather than on their own nature.
