In which of the following pairs of solution will the values of the Van't Hoff factor be the same?
(A) \( 0.05-M K_{4}\left[\mathrm{Fe}(\mathrm{CN})_{6}\right] \) and \( 0.1 M \mathrm{MeSO}_{4} \)
(B) \( 0.05-M K_{4}\left[\mathrm{Fe}(\mathrm{CN})_{6}\right] \) and \( 0.05-M \mathrm{FeSO}_{4} \cdot\left(\mathrm{NH}_{4}\right)_{2} \mathrm{SO}_{4} \cdot 6 \mathrm{H}_{2} \mathrm{O} \)
(C) \( 0.2 \mathrm{M} \mathrm{NaCl} \) and \( 0.1 \mathrm{M} \mathrm{BaCl} 2 \)
(D) \( 0.05-\mathrm{M} \mathrm{FeSO}_{4}\left(\mathrm{NH}_{4}\right)_{2} \mathrm{SO}_{4} .6 \mathrm{H}_{2} \mathrm{O} \) and \( 0.05-\mathrm{M} \mathrm{Na}{ }_{3} \mathrm{PO}_{4} \)
