Solubility product constants $$(K_{sp})$$ of salts of types $$MX, MX_2$$ and $$M_3X$$ at temperature ‘T’ are $$4.0 \times 10^{-8}, 3.2 \times 10^{-14}$$ and $$2.7 \times 10^{-15}$$, respectively. Solubilities (mol dm$$^{-3}$$) of the salts at temperature 'T' are in the order

A

$$MX > MX_2 > M_3X$$

B

$$M_3X > MX_2 > MX$$

C

$$MX_2 > M_3X > MX$$

D

$$MX > M_3X > MX_2$$
