Correct answer
AA-III, B-I, C-II, D-IV

Step-by-step explanation

(A) van't Hoff factor, it is used in measuring colligative properties

i= Normal molar mass  Abnormal molar mass 

(B) kf= Cryoscopic constant or molal freezing constant

(C) Solutions with same osmotic pressure are known as isotonic solutions.

(D) Solutions with same composition of vapour over them are called Azeotrope or azeotrophic mixtures.
