Good exercise promotes growth, fights disease, and helps to control weight.

• A. True
• B. False
• C. Not sure
• D. Sometimes

Answer: (A)

Regular exercise supports development and overall health by strengthening bones and muscles, promoting healthy hormonal responses, and improving body composition. In growing individuals, this activity helps with proper physical development and growth. It also strengthens the immune system and lowers the risk of many diseases, contributing to better disease resistance. For weight control, exercise increases calorie expenditure, helps preserve lean muscle, and improves metabolic efficiency, making it easier to manage or reach a healthy weight. Because these broad, well-supported benefits align with the statement, it is true. The other options are less precise or would imply uncertainty or a lack of benefit, which contradicts the evidence.
