The coagulation values of the electrolytes $\mathrm{Al}{\mathrm{Cl}}_3$ and $\mathrm{NaCl}$ for ${\mathrm{As}}_2{\mathrm{S}}_3$ sol are $0.052$ and 52 respectively. The coagulating power of $\mathrm{Al}{\mathrm{Cl}}_3$ is

 It should be noted that the electrolytes' coagulating abilities are inversely correlated with their coagulating values. 

Thus, 

$\frac{\text{ Coagulation power of }{AlCl}_3}{\text{ Coagulation power of }NaCl}=\frac{\text{ Coagulation power of }NaCl}{\text{ Coagulation power of }{AlCl}_3}=\frac{52}{0.052}\approx 1000$

Therefore, The coagulation values of the electrolytes $\mathrm{Al}{\mathrm{Cl}}_3$ and $\mathrm{NaCl}$ for ${\mathrm{As}}_2{\mathrm{S}}_3$ sol are $0.052$ and 52 respectively. The coagulating power of $\mathrm{Al}{\mathrm{Cl}}_3$ is 1000 times more than that of $\mathrm{NaCl}$

Hence the correct option is (A).
