Hello! I’d be more that willing to help ya out.
I’m going to give you an answer and also an explanation for each choice.
First of all, the answer is choice C.
A is wrong because yes, it’s great to eat right and exercise, but you still have a chance of getting a disease. Those two things do not completely keep you from it.
B is also wrong because inheritance isn’t always the case when someone has a disease. Sometimes, both parents can be in perfect health and the offspring is still able to have health issues.
C is correct because good health habits do not keep you completely from disease, but they decrease your chances of developing a disease. It is less likely to happen then.
D is incorrect because perfect health can never be promised no matter what you eat or what you do. Everyone always has some sort of health risks, even if they are the healthiest person alive.
I hope my reasoning assisted you in the best way! Happy studying.
