Answer:
D. body composition
Explanation:
Body composition is a concept that concerns the proportions of muscle, fat, bone and other vital parts of the body. From a functional and performance point of view, body mass, or weight measured in the balance, may not be such a useful measure because it masks the relative contribution of different tissues to the resulting value. Imagine the figure of two men of similar height and weight but different body compositions. Two men of approximately 1,80m and 105 kg. Both would be considered overweight according to conventional tables of epidemiological distribution of body mass index (BMI). However, one is visibly overweight (right side) and the other is an athletic, conditioned man. The difference between them is body composition.
Body composition along with muscular endurance, cardiovascular endurance, muscle strength and flexibility are the main markers of physical fitness.
Scientific research would be the best source of information.
