Answer choices

This doesn't explain the situation because it only says that stress and pollution can exacerbate existing cardiovascular disease. The residents of the town don't have any cardiovascular disease at all.
This introduces the idea that very low blood sugar can protect against cardiovascular disease, but it says the people of Limone have normal blood sugar levels. So this doesn't explain why they don't have cardiovascular disease.
This explains why the residents aren't getting cardiovascular disease. They have a genetic trait that helps prevent the disease.
This doesn't tell us anything about the people of Limone. We don't know if their diets are made up of more monounsaturated fats or some other kind of fat that is less healthy.
