The correct answer is B. Wellness is related to balanced improvement in all six dimensions of health.
Explanation:
The term "wellness" is used to refer to a positive and balanced health state; this includes six different dimensions: physical health, emotional health, social health, environmental health, intellectual health, and spiritual health. This idea is important because each of these dimensions is connected and the individual will need to achieve a positive state in all of these to experience real wellness.
For example, you might be physically well if you eat healthily and do exercise but if you are not emotionally stable or do not have positive relationships with other people then you will not experience wellness. According to this, a good description of wellness is "Wellness is related to balanced improvement in all six dimensions of health".
