Consider separate solutions of `0.500 M C_(2)H_(5)OH(aq)`,`0.100 M Mg_(3)(PO_(4))(aq)`,`0.250 M KBr(aq)`, and `0.125 M Na_(3)PO_(4)(aq)` at `25^(@)C`. Which statement is true about these solutions, assuming all salts to be strong electrolytes?

A

0.125 M `Na_3 PO_4 (aq)` has the highest osmotic pressure.

B

0.500 M `C_2H_5OH(aq)` has the highest osmotic pressure.
