The coagulation values in millimoles per litre of the electrolytes used for the coagulation of $$As_2S_3$$ are given below:
I. $$(NaCl) = 52$$
II. $$(BaCl_2) = 0.69$$
III. $$(MgSO_4) = 0.22$$
The correct order of their coagulating power is

A

II > I > III

B

III > II > I

C

III > I > II

D

I > II > III
