I believe the correct answer is A. All of the other choices except A is related or associated with chemical equilibrium and should follow Le Chatelier's Principle. We take in oxygen and it is one of the reactants for cellular respiration where one of the products is CO2 and is the one being released not O2.
The answer is a)release of oxygen in the human body
Explanation:
The principle of Le Chatelier says that if a system that is in equilibrium is subjected to a change in conditions, this system will move to a new position in order to compensate for the effect that altered it and thus return the state of equilibrium.
The human body does not release oxygen, on the contrary, this process involves the fractionation of pyruvic acid producing carbon dioxide and water, together with the production of ATP. In other words, cellular respiration is a metabolic process in which cells reduce oxygen to produce energy and water.
