Best answer
Right choice is (a) Vapor pressure lowering

For explanation: Vapor pressure lowering is the alternative name for boiling point elevation. The vapor pressure of an aqueous solution is less than that of pure water at the same temperature. Therefore the boiling point of the solution will be higher than that of the water.
