Final answer:
For sedentary individuals or beginners in cardiovascular training, the (A) fat-burning zone, which is low intensity and keeps heart rate between 60-69% of the maximum, is most appropriate.
Explanation:
The most appropriate training zone for sedentary individuals or those who are just beginning a cardiovascular training program is the fat-burning zone.
This low intensity aerobic activity keeps the heart rate between 60 and 69% of maximum heart rate. Starting in this zone is beneficial because it helps the individual burn a significant percentage of calories from fat while maintaining a level of intensity that is manageable and safe for their current fitness level.
It is a sustainable way to commence their cardiovascular training, avoiding the risks of overexertion that come with higher intensity zones.
