○ a
○ b
○ c

Explanation:

Cardiorespiratory fitness relates to the ability of the heart and lungs to supply oxygen during physical activity. As people age, physiological changes (like decreased lung function, reduced heart efficiency) typically lead to a decline in cardiorespiratory fitness, unless specific exercise regimens are followed, but the general trend is decline. So option B is correct.

Answer:

B. decline
