Answer:
Option e. They all have about the same vapor pressure.
Explanation:
If we assume the same molality in each solution and the gases are dissolved in the same amount of water, we would assume the same mole fraction for each.
The moles of solute are the same in each solution.
So we assume, i = 1, as they are nonvolatile solutes
The solvent is the same in each solution → water
ΔP = P° . Xm . i
No numbers in the formula are modiffied, that's why the only option which matches, is e.
