The three factors that can be defined as essential parts of one’s overall health.

a. physical, scientific, and mental and emotional
b. mental and emotional, professional, and social
c. social, mental and emotional, and physical
d. environmental, scientific, and mental and emotional

The answer is C- social, mental/ emotional, and physical

The best definion of one's overall health comes from World Health Organization. They say  that health is a state of physical, mental and social well-being. These three components are more important than just the absence of affections and diseases.
This definition changed over the years, and now is more about the value to the community(a good of all) than to the individual.

physical- This is the most obvious one. Once we have a disease, part of our systems are affected that will reflect in our health.

social-  Humans are social beings; we need to be accepted in society; we can't live alone.

mental- anxiety, uncertainties, constant weariness of mental energies, etc., lead to fatigue and psychosomatic problems.
