b. the ability of your heart to pump blood to your cells

Explanation:

Cardiorespiratory endurance refers to the capacity of the heart and lungs to supply oxygen during sustained physical activity. Option A describes this as the ability of heart and lungs to work during prolonged exercise. Option B focuses only on the heart's blood - pumping to cells, not endurance. Option C's mention of fending off asthma is incorrect as cardiorespiratory endurance is not about that. Option D describes a part of the circulatory process, not endurance.

A. the ability of your heart and lungs to work during prolonged exercise
