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:

  • A
    $MX > MX_2 > M_3X$
  • B
    $M_3X > MX_2 > MX$
  • C
    $MX_2 > M_3X > MX$
  • D
    $MX > M_3X > MX_2$
