Which of the following liquid pairs shows a positive deviation from Raoult's law?

Which of the following is an ideal solution?

Which of the following mixtures is an ideal solution?

Liquid $A$ and $B$ form an ideal solution. The vapour pressure of pure liquids $A$ and $B$ are $350 \ mm \ Hg$ and $750 \ mm \ Hg$ respectively at the same temperature. If $x_A$ and $x_B$ are the mole fractions of $A$ and $B$ in the solution,and $y_A$ and $y_B$ are the mole fractions of $A$ and $B$ in the vapour phase,then:

Which of the following does not show negative deviation from Raoult's law?
