Answer : The correct options are, (A), (C) and (D)
Explanation :
Le-Chatelier's principle : It states that if any change in the variables of the reaction, then the equilibrium will shift in that direction where the effect will be minimum.
The balanced equilibrium reaction will be,

As the concentration of
are decreased, the equilibrium will shift in a direction where concentration of
is increasing and thus the dissociation of acid will increase to supply more of
ions. During this process the reaction will move to the right direction.
In the given equilibrium reaction when the
are added then the
ion will combine with
ion to form water.
Hence, the correct options are, (A), (C) and (D)
