Solution

The correct option is D $M X > M_{3} X > M X_{2}$
MX: $K_{s p} = S^{2} = 4 \times 10^{- 8}$
$\Rightarrow S = 2 \times 10^{- 4}$
$M X_{2} : K_{s p} = 4 S^{3} = 3.2 \times 10^{- 14} \Rightarrow S = 2 \times 10^{- 5}$
$M_{3} X : K_{s p} = 27 S^{4} = 2.7 \times 10^{- 15} \Rightarrow S = 10^{- 4}$
Order of solubility is $M X > M_{3} X > M X_{2}$
