Which statement best describes the impact of regular exercise on health?

• A. It improves flexibility
• B. It increases fatigue
• C. It promotes growth, fights disease, and helps to control weight
• D. It has no health benefits

Answer: (C)

Regular exercise strengthens the body and supports overall health by improving heart and lung function, building muscle and bone, helping regulate body weight, and boosting the immune system. This combination—promoting growth and development, fighting disease, and helping control weight—best describes the broad health benefits of consistent activity. While flexibility can improve with exercise, and regular activity usually reduces fatigue over time, the statement capturing all these major benefits is the most accurate, whereas claiming there are no health benefits is clearly false.
