Which of the following is a method to ensure a healthy life?

Choosing all of the above is a comprehensive approach to ensuring a healthy life because it recognizes that health is multifaceted. Regular exercise is vital as it not only helps in maintaining physical fitness and managing weight but also boosts mental health through the release of endorphins, which can alleviate stress and improve mood.

Balanced nutrition is equally important, as it provides the body with essential nutrients needed for optimal functioning. A well-rounded diet can prevent chronic diseases, bolster immune system functionality, and support overall physical health.

Mental wellness cannot be overlooked, as it plays a crucial role in overall health. Practices that enhance mental well-being, such as mindfulness, stress management, and seeking support when needed, contribute significantly to one's quality of life.

Together, these elements create a holistic framework for healthy living, emphasizing that physical, nutritional, and mental health are interconnected. Focusing on just one aspect, like exercise or nutrition alone, would not be as effective in promoting overall well-being, highlighting the importance of a balanced approach.
