Answer: Option (B) is the correct answer.
Explanation:
When we add a non-volatile solute in a solvent then due to the impurity added to the solution there will occur an increase in the boiling point of the solution.
This increase in boiling point will be known as elevation in boiling point.
This increase in boiling point arises because particles of the non-volatile solute are aligned at the surface of solution due to which solvent particles are not able to escape out of the solution.
Hence, high amount of heat is required for the solute particles to escape out of the solution. Therefore, an increase in boiling point will occur.
Thus, we can conclude that boiling point elevation is the colligative property that means a solution typically has a measurably higher boiling point than a pure solvent alone.
