Which of the Following Statements Regarding the Solutions and the Van

Which of the following statements regarding the solutions and the van 't Hoff factor is NOT correct?

A) Nonideal behavior can occur in solutions containing ions when the ions do not behave as independent particles in solution.
B) Theoretical van 't Hoff factors often predict colligative properties of solutions with concentrations of about 0.01 m or less.
C) In dilute solutions,the experimental van 't Hoff factor for a compound is always greater than one.
D) As concentrations increase,the probability of ion pairing increases.
E) The deviation from ideal behavior generally increases as the charge on dissolved ions increases.
