We know vant hoff factor, i is directly proportional to depression in freezing point (ΔTf) which is dependent on the number of ions formed in aqueous medium. Here all salts are assumed to be 100% dissociated so their α (degree of dissociation) = 1.
 
4th salt is supposed to have highest freezing point.
