Explanation:
We must remember that when a constraint such as a change in concentration, pressure or temperature is imposed on a reaction system in equilibrium, the equilibrium position will shift in such as way as to cancel the constraint.
If more of A or more of B is added to the system, the equilibrium position will shift towards the right and the solution becomes clear and colorless.
If C is added to the system, the equilibrium position will shift towards the left and the solution colour turns blue.
If A is removed from the system, the equilibrium position is shifted towards the left and the solution once again turns blue.
If C is removed from the system, the equilibrium shifts towards the right and the solution turns clear and colorless
