Since the options have not been given the question is incomplete. The complete question is as follows:
The health care provider is discussing major risk factors for coronary artery disease (CAD) with a client. The most important information for the provider to include would be:
a)History of cigarette smoking and elevated blood pressure 
b)Physical inactivity and high serum high-density lipoprotein cholesterol
c)High serum high-density lipoprotein and diabetes 
d)Advanced age and low serum total and low-density lipoprotein cholesterol
Answer:  a)History of cigarette smoking and elevated blood pressure 
Explanation:
CAD is a plaque or clot development in the walls of the arteries that supplies blood to the entire body. Plaque develops due to deposition of cholesterol and other substances in the arteries. This affects the blood flow.
The chemicals in the cigarette smoke develops plaque or clots in the blood vessels or arteries. This affects the blood pressure. Thus the blood pressure get elevated. The chemicals in the smoke causes the blood vessels to get swollen and inflamed. This increases the risk of strokes.

Its not D because it doesn't show signs of him saying that he wants or is going to give up, and if he were to give up then why is there no context clues.
