b. nonsmokers are twice as likely to develop cardiovascular disease.
c. nonsmokers and smokers are equally likely to develop cardiovascular disease.
d. nonsmokers are half as likely to develop cardiovascular disease.

Nonsmokers are half as likely to develop cardiovascular disease.

Explanation:

Tobacco is highly hazardous to health, not only does it affect the respiratory system, but when the chemicals present in tobacco, such as nicotine or tar go into the blood through the lungs, they can cause severe damage to the circulatory system by thickening the arterial walls and thus reducing circulation.

Non-smokers are half as likely to develop cardiovascular disease as compared to smokers.

Further Explanation:

Smoking is the major cause of death in most of the country. It causes many severe diseases named as:

In non-smokers, clean and oxygen-rich air is breath in and tiny dust particulate enters with air that is trapped by the cilia. Smoke consists of harmful substances and chemicals, which cause inflammation in the lungs. Because of this inflammation, lungs release mucus and cause severe problems. They cause a major disease named as atherosclerosis. In this disease, the wall and lining of the arteries became thick. Also, the abruption of oxygen into the blood is decreased because of the harmful chemicals which are present in a cigarette.

Thus, due to this reason, a smoker is more prone to cardiovascular disease than non-smokers. In non-smokers, cardiovascular disease can occur due to some other reason.
