Identify the following statement as true or false and choose the correct explanation. "For solutions with the same molarity at the same temperature, the pressure needed for reverse osmosis of a sodium chloride solution will always be less than the pressure needed for a calcium chloride solution."

A) True, because the molar mass of sodium chloride is smaller.
B) True, because the van 't Hoff factor is smaller for sodium chloride.
C) False, because the van 't Hoff factor is smaller for sodium chloride.
D) False, because the van 't Hoff factor is larger for sodium chloride.
E) True, because the van 't Hoff factor is larger for sodium chloride.
