Which set is not correct for the solubility product $\left(K_{sp}\right)$ solubility (Sg/litre) of sparingly soluble salt ${\text{A}}_{\text{3}}{\text{B}}_{\text{2}}$(mol. Wt. M) in water:.

• A

  ${\text{K}}_{sp}{\text{=108S}}^{\text{5}}$

• B

  ${\text{K}}_{sp}\text{=}{\left[\frac{\text{3S}}{\text{M}}\right]}^{\text{2}}{\left[\frac{\text{2S}}{\text{M}}\right]}^{\text{2}}$

• C

  ${\text{K}}_{sp}\text{=}{\left[{\text{3A}}^{\text{2+}}\right]}^{\text{3}}{\left[{\text{2B}}^{\text{3-}}\right]}^{\text{2}}$

• D

  $\left[{\text{B}}^{\text{3-}}\right]\text{=}\frac{\text{2S}}{\text{M}}$
