In a reaction $A + B ⇌ C + D,$ Le Chatelier's principle asserts that an equilibrium between $A$ and $B$ producing $C$ and $D$ can be shifted towards $C$ and $D$ by
(i) increasing the concentration of $A$ or $B$

(ii)increasing the concentration of $C$ or $D$

(iii) decreasing the concentration of $A$ or $B$
