(A)A decrease in boiling point of solution
(B)An increase in boiling point of the solutionCorrect
(C)A decrease in freezing point of the solutionCorrect
(D)An increase in freezing point of the solution.

Answer: (B),(C)

Solution

Lowered vapour pressure of the solvent means the solution must be heated to a higher temperature to reach the external pressure (boiling point rises, b) and the solid
