A)                 It follows from Le Chatelier?s principle

B)                 Of common-ion effect

C)                 Ionic product \[(B{{a}^{++}}),\]\[(C{{l}^{-}})\]remains constant in a saturated solution

D)                 At constant temperature, the product \[(B{{a}^{2+}}),\] \[{{(C{{l}^{-}})}^{2}}\] remains constant in a saturated solution
