    Answer: Option (B) is the correct answer.

    Explanation:

    According to Le Chatelier principle, when a system is in equilibrium then any change in the reaction will shift the equilibrium in a direction which is opposing the change.

    For example, when heat is added to a system the molecules will gain kinetic energy. So, rate of reaction will increase hence, product formation will increase but equilibrium will shift in the opposite direction.

    Hence, we can conclude that according to Le Chatelier's principle, the reaction shifts to remove the heat if heat is added to a system.
