Consider separate solutions of \[0.500M{{C}_{2}}{{H}_{5}}OH(aq),\] \[0.100M\,M{{g}_{3}}{{(P{{O}_{4}})}_{2}}(aq),0.250\,MKBr(aq)\]and \[0.125MN{{a}_{3}}P{{O}_{4}}(aq)\]at \[25{}^\circ C\]. Which statement is true about these solutions, assuming allsalts to be strong electrolytes ?   JEE Main  Solved  Paper-2014

A) \[0.125MN{{a}_{3}}P{{O}_{4}}(aq)\]has the highest osmotic pressure.

B) \[0.500M{{C}_{2}}{{H}_{5}}OH(aq)\]has the highest osmotic pressure.

C) They all have the same osmotic pressure.

D) \[0.100MM{{g}_{3}}{{(P{{O}_{4}})}_{2}}(aq)\]has the highest osmotic pressure.
