Answer:

The correct option is C.

Explanation:

From the information given in the question, it is obvious that De-Shawn created two models of the heart in order to show the differences that exist between the heart of a smoker and that of a non smoker. Smoking is an addictive habit that has great negative effects not only on the circulatory system of smokers alone but also on the whole body system.

Smoking normally damages the functions of the circulatory system by destroying the lining of the arteries; this leads to accumulation of fatty deposits that narrow the width of the arteries. The narrow arteries will hinder blood from flowing normally and this can lead to different types  of medical conditions such as stroke, heart attack, heart failure, coronary heart diseases, etc.
