An ideal solution is defined as one where the solute-solute, solvent-solvent, and solute-solvent interactions are very similar. Therefore, statement III is correct. Raoult's law states that the partial vapor pressure of each component in a mixture of liquids is directly proportional to its mole fraction in the mixture. An ideal solution follows Raoult's law, so statement II is also correct. However, an ideal solution does not necessarily have to follow the ideal gas law (statement I), nor do the interactions have to be quite different (statement IV).
