The answer to this is letter C. Based on the symptoms that the man has displayed, he had this condition before he died. He has shown that he had a persistent cough that sometimes lasted for months. There are two main reasons why some people are more prone to chronic bronchitis.

It is because of constantly being exposed to air pollution and smoking. The inflamed bronchial tubes usually come up with more mucus that will make it more difficult for people who have this condition to breathe. People who are also exposed to a lot of dust for an extended period of time may be more prone to acquiring this condition more than others.

Chronic bronchitis -(c) correct. chronic bronchitis is defined clinically as a person who has persistent cough with sputum production for at least 3 months in at least 2 consecutive years. air pollution and smoking are key causes for chronic bronchitis.(a) incorrect. though lung cancers are more common in persons who smoke, his findings are not explained by a mass lesion, and his symptoms have persisted for years.(b) incorrect. congestive heart failure will produce pulmonary edema, if it is primarily left heart failure. if severe, there can be rusty colored sputum.(e) incorrect. as a smoker, he is at risk for development of emphysema, but this does not explain his sputum production. sometimes, smokers have elements of both emphysema and chronic bronchitis.(g) incorrect. bronchiectasis is not a typically complication of smoking.
