An ideal solution is a type of liquid-liquid solution where the solute-solute, solvent-solvent, and solute-solvent interactions are very similar. This means that Raoult's law is obeyed, which states that the vapor pressure of each component in the solution is proportional to its mole fraction in the solution. However, the solution does not necessarily have to follow the ideal gas law (PV = nRT). Therefore, options I and II are incorrect, and option III is correct. Option IV is incorrect as it contradicts the definition of an ideal solution.
