    A) Osmotic pressure (\[\pi \]) of a solution is given by the relation \[\pi \] = MRT where M is the molarity of the solution.

    B) The correct order of osmotic pressure for 0.2 M aqueous solution of each solute is \[CaC{{l}_{2}}<NaCl>C{{H}_{3}}COOH>\] glucose.

    C) Two solutions of sucrose of same molality prepared in different solvents will have same elevation in boiling point.
