Explanation:

As people age, their bodies undergo various physiological changes. The heart and lungs, which are crucial for cardiorespiratory fitness, also experience age - related decline. The heart muscle may become stiffer and less efficient at pumping blood, and the lungs may lose some of their elasticity. Regular exercise can slow down this decline to some extent, but it cannot completely stop the natural aging process of these organs. So, in general, cardiorespiratory fitness levels tend to decline with age.

Answer:

B. decline
