B. Participate in more activities like weight training
Explanation:
Sarcopenia is a disease in which an individual starts losing muscle tissues due to aging and no exercise. Therefore, in this condition, participation in weight training (which includes eating healthy food) is recommended because it will help develop more muscle fibers and thin and weak muscle fibers will become stronger.
Conclusively, sarcopenia happens due to lesser physical activities in individuals and it is usually treated with appropriate muscle training.
