Solution

The correct option is B False
On diluting the solution, its relative lowering of vapour pressure changes
since it is a colligative property. But molality of the solution will also change
as the mass of the solvent will change on dilution and molality depends on
the mass of solvent too [molality = (moles of solute) / (mass of solvent in kg)]
