C. Body composition
Explanation:
by elimination- here are the definitions of each:
<u>Physical agility</u>: Agility is defined as “a skill-related component of physical fitness that relates to the ability to rapidly change the position of the entire body in space with speed and accuracy.”
<u>Muscular endurance:</u> Endurance is the ability of an organism to exert itself and remain active for a long period of time, as well as its ability to resist, withstand, recover from, and have immunity to trauma, wounds, or fatigue. It is usually used in aerobic or anaerobic exercise.
<u>Body composition:</u> In physical fitness, body composition is used to describe the percentages of fat, bone, water and muscle in human bodies. Because muscular tissue takes up less space in the body than fat tissue, body composition, as well as weight, determines leanness.
<u>Cardiovascular fitness: </u> Cardiovascular fitness refers to the physical work capacity of an individual, in the form of amount of oxygen capacity per kilogram of body weight over time (mL/kg/min)
