What is body composition?

Body composition refers specifically to the proportion of different components that make up the body, primarily focusing on the ratio of body fat to lean mass, which includes muscle, bones, organs, and fluids. Understanding body composition is vital in physical education and health, as it provides insight into an individual's fitness level and overall health status.

This measure goes beyond just weight, as it distinguishes between fat mass and lean mass—important for assessing health risks associated with excess body fat or insufficient muscle mass. Therefore, option A encapsulates the essential concept of body composition effectively, highlighting the importance of not just considering weight but understanding the quality of that weight in terms of health and fitness.
