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 $\;25^{0}C\;$.Which statement is true about these solutions , assuming all salts to be strong electrolytes ?

(a) They all have the same osmotic pressure.(b) 0.100 M $\;Mg_{3}(PO_{4})_{2}(aq)$ has the highest osmotic pressure.  (c) 0.125 M $\;Na_{3}PO_{4}(aq)\;$ has the highest osmotic pressure.(d) 0.500 M $\;C_{2}H_{5}OH(aq)\;$ has the highest osmotic pressure.
