(D) For $MX$: $K_{sp} = S^2 = 4 	imes 10^{-8} \Rightarrow S = 2 	imes 10^{-4} \ M$.For $MX_2$: $K_{sp} = 4S^3 = 3.2 	imes 10^{-14}$ $\Rightarrow S^3 = 0.8 	imes 10^{-14} = 8 	imes 10^{-15}$ $\Rightarrow S = 2 	imes 10^{-5} \ M$.For $M_3X$: $K_{sp} = 27S^4 = 2.7 	imes 10^{-15}$ $\Rightarrow S^4 = 0.1 	imes 10^{-15} = 1 	imes 10^{-16}$ $\Rightarrow S = 10^{-4} \ M$.Comparing the values: $2 	imes 10^{-4} > 1 	imes 10^{-4} > 2 	imes 10^{-5}$.Therefore,the order of solubility is $MX > M_3X > MX_2$.

Solubility product $(K_{sp})$ of the salts $MX$,$MX_2$,and $M_3X$ at temperature $T$ are $4 \times 10^{-8}$,$3.2 \times 10^{-14}$,and $2.7 \times 10^{-15}$ respectively. The solubilities of these salts at temperature $T$ are in the order:
