Solution

The correct option is C $A l_{2} {(S O_{4})}_{3}$
As $S b_{2} S_{3}$ sol. carries a negative charge so it can be coagulated by positive ions.
And greater the valency of the flocculating ion, greater is its power to cause precipitation.
In all given compounds $A l_{2} (S O_{4})_{3}$ has positive cation with highest valency of $+ 3$ .
