The most likely TRUE statement about cardio fitness is:

It brings oxygen into the blood and requires people to breathe harder.

Cardiovascular fitness involves physical activities that elevate heart rate and improve the efficiency of the cardiovascular system, leading to better oxygen delivery to the muscles and a greater requirement for respiration. The other statements are either false or misleading regarding the role of cardio fitness in a fitness plan or incorrect in their recommendations.
