ANS:D - all (a), (b) & (c).

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 generalization is based on the assumption that: "component molecules are non-polar and no chemical combination or molecular association between unlike molecules takes place in the formation of the solution." This assumption is crucial for the application of Raoult's law to solutions. It implies that the interactions between the molecules of the solute and solvent are similar to those between the solvent molecules themselves. Therefore, the correct answer is option (c).
