Solution

The correct option is C higher
Elevation in boiling point :- The boiling point of a liquid is that temperature at which its vapour pressure becomes equal to the atmospheric pressure. i.e. 760 mm of Hg.
When a non-volatile solute is dissolved in a pure solvent, its vapour pressure is decreased. The difference of boiling points of the solution and pure solvent is called elevation in boiling point.
So, boiling point of solution is higher than the boiling point of pure solvent.
