A. Not 100% sure why, but the trend is that the lower the vapor pressure, the higher the boiling point and the lower the boiling point, the higher the vapor pressure. <p> It wants lowest, so you're looking for the molecule with the highest boiling point. The bigger the molecule, the higher the BP. CaO is the highest, then LiBr, CH3OH, then CO. <p> Best of luck-
