Solution

The correct option is A $A l^{3 +}$
Hardy-Schulze rule : the greater is the valence of the oppositely charged ion of the electrolyte added to a colloidal solution, the faster is the coagulation of the colloidal solution.
Flocculating power is inversely proportional to coagulating power.
For highest flocculating power, coagulating power should be minimum and Al3+ have lowest coagulating power.
