Answer;

C. The equilibrium position will shift away from what was added to lower its concentration.

Explanation; Le Chatelier's principle states that; if a system at equilibrium is disturbed, the equilibrium position will shift to counter the effects of the disturbance. At equilibrium, the system is disturbed when a change in conditions forces it temporarily out of equilibrium. There are three common disturbances:

1. Change in concentration.

2. Change in pressure (caused by a change in volume).

3. Change in temperature.
