Solution

The correct option is B the relative lowering of vapour pressure is proportional to amount of solute
According to Raoult's law, for dilute solutions containing non volatile solute, the relative lowering at vapour pressure is proportional to the mole of solute or inversely related to mole fraction of solvent.
