Raoult’s law states that ‘the equilibrium vapor pressure that is exerted by a component in a solution is proportional to the mole fraction of that component’. This generalisation is based on the assumption that the________________?

A. Sizes of the component molecules are approximately equal
B. Attractive forces between like and unlike molecules are approximately equal
C. Component molecules are non-polar and no chemical combination or molecular association
between unlike molecules takes place in the formation of the solution
D. All A., B. & C.
