The correct choice is B.
Engaging regularly in physical activity, which includes aerobic workouts as well as balance and strength training, yields numerous health benefits, promotes healthy aging, and extends the independence of the elderly.
From a physiological perspective, physical exercise can:
* Enhance functional abilities (pulmonary, cardiovascular, muscular function) and psychological well-being.
* Improve body composition (reducing body fat, increasing muscle mass and bone mineral density)
* Lower the likelihood of various health issues (respiratory, cardiovascular, muscular, joint, metabolic, neurodegenerative conditions, cancers)
* Mitigate the impact of aging and boost the lifespan without disabilities.
