C. In case of dissociation of solute particles in a solution, the van't Hoff factor is more than unity because th
Step-by-step solution
At the freezing point of a solution, the vapour pressure of the liquid solvent in the solution is equal to the vapour pressure of the pure solid solvent. Thus, statement (A) is incorrect. A hypotonic solution has a lower osmotic pressure and is less concentrated compared to the other solution. Thus, statement (B) is incorrect. In the case of dissociation of solute particles, the number of particles in the solution increases. The van't Hoff factor i is greater than 1 . Since i = Normal molar mass Observed molar mass
