Answer:
D is the correct option.
Step-by-step explanation:
In order to explain all the solutes from the excersise, the lowest molar mass will give the solution, the highest boiling point.
ΔT = Keb . m
Molality = mol of solute / 1kg of solute
Mol of solute = mass / molar mass
If the molar mass↓ it's small, mol of solute will be↑
Mol of solute ↑ , generates high molality
ΔT ↑ = Kf . m ↑
If the molality is high, the difference between the temperautes, will be high, so the boiling point from solution, will be higher.
