Answer:
d. Exercise increases the body's demand for oxygen.
Explanation:
More oxygen is needed during exercise by the body as compared to normal condition because our body needs energy which is only generated in the process of cellular respiration. In cellular respiration, glucose molecule is broken down by mitochondria of the cell and energy is generated in the form of adenine tri phosphate (ATP) which is used for performing muscular activity. So that's why oxygen requirement is more during exercise.
