The best comparison between body fat and lean muscle tissue is:
A. High levels of body fat increase a person's risk for certain diseases.
This statement is accurate, as excessive body fat is often associated with an increased risk of various health issues, including diabetes, heart disease, and certain cancers.
C. High levels of lean muscle tissue make a person's metabolism burn calories efficiently. is also true, as muscle tissue is metabolically active and helps increase the resting metabolic rate, leading to more calories being burned.
However, the other two statements, B and D, are not accurate. High levels of body fat do not make metabolism work efficiently, and high levels of lean muscle tissue do not increase disease risk; in fact, they are usually associated with better health outcomes.
