1. A-III, B-I, C-II, D-IV
2. A-III, B-I, C-IV, D-II
3. A-II, B-II, C-I, D-IV
4. A-I, B-III, C-II, D-IV

Correct answer: A-III, B-I, C-II, D-IV

Solution

The correct option matches the van't Hoff factor (i) with normal molar mass, as it indicates the number of particles in solution; the cryoscopic constant (kf) is related to freezing point depression; isotonic solutions have the same osmotic pressure; and azeotropes exhibit abnormal molar mass due to their unique vapor-liquid equilibrium.
