Answer:
Correct option is
A
Potassium sulphate
Urea and glucose do not dissociate in solution. Sodium chloride gives two ions and potassium sulphate gives three ions per formula unit.
Therefore, the effective number of particles is maximum in potassium sulphate , and it shows the maximum depression in freezing point.
