ANSWER
Option C
Step-by-step explanation
Le Chatelier's principle state when an external constriaints such as temperature, pressure, concentration is imposed on a system in equilibrium, the system will shift so as to annul or neutralize the effect of the constraints.
This implies the temperature of the system is increased or decreased, the system will react to attain a new equilibrium
Therefore, when the equililbrium of the system is disturbed, the system will react to re-establish equilibrium
Hence, the correct answer is option C
