Answer:
B
Step-by-step explanation:
When a person is obese, their heart has to work very hard to pump blood through their whole body, having high blood pressure just increases the strain on the heart. When people have high levels of LDL Cholesterol, the cholesterol may develop fatty deposits in the blood vessels that make it even harder for blood to flow through the arteries, increasing even more the strain on the heart. When they exercise, blood flows better through their vessels and decreases the strain on their heart, but when they don't exercise, fatty deposits may build up over time in their blood vessels, leading to heart disease.
