Explanation / Answer

1-

colligative properties are properties of solutions that depend on the ratio of the number of solute particles to the number of solvent molecules in a solution, and not on the type of chemical species present.

colligative properties are Vapour pressure lowering, Freezing point depression, Boiling point elevation, Osmatic pressure.

So density elevation is not a colligative property.

Hence option (D) is correct.
