The assertion is true because adding a solute to a solvent does indeed increase the boiling point of the resulting solution. This is due to the fact that the presence of solute particles in the solvent causes a decrease in the vapour pressure of the solvent, which in turn leads to an increase in the boiling point. The reasoning is the correct explanation of the assertion because the colligative property of boiling point elevation is responsible for this phenomenon.
