c. it activates skeletal muscles and skin tissue.

d. it increases blood flow throughout the body.

Explanation:

Cardiorespiratory fitness relates to the efficiency of the heart and lungs. Option A: Mental stress reduction is a secondary benefit, not the greatest from cardiorespiratory fitness. Option B: Waste removal is part of bodily functions, but not the primary great benefit of cardiorespiratory fitness. Option C: Activating skeletal muscles and skin tissue is not the main benefit of cardiorespiratory fitness (it's more about heart and lung function). Option D: Cardiorespiratory fitness improves the heart's ability to pump blood, thus increasing blood flow throughout the body, which is a core and major benefit as it delivers oxygen and nutrients to tissues.

Answer:

D. It increases blood flow throughout the body.
