Effect on vapour pressure of dissolving substance

Give me answer of this question. When a substance is dissolved in a solvent the vapour pressure of the solvent is decreased. This results in: (a) An increase in the b.p. of the solution (b) A decrease in the b.p. of the solvent (c) The solution having a higher freezing point than the solvent (d) The solution having a lower osmotic pressure than the solvent
