B Correct answer
Explanation

Sweat is the body's cooling mechanism, not an indicator of calorie burn or cardiovascular effectiveness. You can sweat without significant calorie expenditure (hot environment) and burn substantial calories without visible sweat (swimming, cold weather running). Cardiovascular fitness is better measured by heart rate, endurance, and VO2 max improvements.
