The answer is A. Accomplishing daily tasks without undue fatigue.Regular physical activity strengthens the heart, lungs, and muscles, which improves endurance and stamina. Over time, this allows individuals to complete everyday activities—such as climbing stairs, carrying groceries, or walking long distances—without becoming overly tired. The other options describe negative outcomes: increased fatigue, risk of high blood pressure, and higher body fat levels are actually consequences of inactivity. Physical activity also reduces risks of chronic diseases like diabetes and heart problems, improves mood, and supports better sleep. Thus, the correct answer highlights the positive, long-lasting effect of exercise: being able to live a healthier, more energetic, and independent life.
