As we have learnt ,

\mathrm{\Delta T_{f}=i \cdot K _{f} \cdot m}

For equimolar solutions, the freezing point decreases as the van't Hoff factor increases.

Since, \mathrm{Al}_{2}\left(\mathrm{SO}_{4}\right)_{3}  forms the greatest number of ions in solution, it has the greatest van't Hoff factor and as a result, has the lowest freezing point.

Hence, the correct answer is Option (1)
