Which one of the following choices best represents an advantage of cardiorespiratory fi
tness

While you didn't provide any choices, we can surely say that one of the most obvious would be that you need longer and more intense physical stimulation (running a lot or performing a certain physical activity very intensely) to become fatigued compared to somebody who doesn't have any cardiorespiratory fitness. They would tire out much easily and would develop a higher heart rate much faster. 

Call the cops or tell an adult u trust

Dialect is probably part of the answer
