The correct answer is C.
Skin cancer is unaffected by physical activity as once you have skin cancer doing anything physical does not alter the cancer, it doesn't make it worse or better. Type 2 diabetes, hypertension and depression can all be affected by physical activity. All of these conditions can be helped and improved with exercise or moving your body more than you usually would by doing a fun activity. Exercise releases endorphins which makes you feel better, it lowers blood pressure and helps you to lose weight.
