Education may have a certain influence on health, but it is not a direct or significant influence. However, genetics is a factor that influences health significantly. As we know, through genetics we inherit traits from our parents that cannot be changed, among these traits we can inherit disease and in addition, genetic errors can influence our health causing syndromes and disease.
In addition, public policies and the dress code of schools are factors that influence our health. Public policies should promote our well-being and quality medical services, while the schools' dress code is established to enable our bodies to be skilled, comfortable and healthy for school activities.
The factor that does not directly influence health is letter B - education. Education actually improves your intellectual wellness. All the other choices are wrong because they all affect some parts of your health like emotional, physical and social. Hope this helps.
