Consider separate solutions of 0.500 M `C_(2)H_(5)OH_((aq)), 0.100 M Mg_(3)(PO_(4))_(2(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_(2)H_(5)OH_((aq))` has the highest osmotic pressure.

C

They all have the same osmotic pressure.

D

`0.100 M Mg_(3)(PO_(4))_(2(aq))` has the highest osmotic pressure.
