I believe the answer is C, the temperature at which the solution boils is raised. When a solute is added to a solvent, the boiling point will be higher than the boiling point of the pure solvent. Such that when anything is dissolved in a solvent say water, the solution will boil at a higher temperature than pure solvent (water) would. The effect of adding solute to a solvent however, has an opposite effect on freezing point of a solution as it does on the boiling point.
