The correct answer to the question: Chronic Obstructive Pulmonary diseases (COPD), include:____, would be, D: a and b are correct.

Explanation:

COPD, or best known as Chronic Obstructive Pulmonay Disorder, is the general name given to a disease in which the lungs are incapable of performing their task of oxygen and carbon dioxide exchange, because of an obstruction either of the airways, or the alveoli, which are the sacks in which the actual exchange takes place. This obstruction can happen either because of an overproduction of mucus, or because the airways become fibrous, and therefore, oxygen cannot be exchanged. The other reason is when the alveoli are damaged and destroyed and air sacks form in the lungs. In COPD, we have two types: Chronic Bronchitis, in which due to continuous coughing, and mucus production, the bronchi become inflamed and fibrous and therefore exchange is much more difficult. In the second form, we have emphysema, in which the constant coughing starts affecting the lining of the alveoli, until it can literally be destroyed and pockets of air can form inside the actual lung tissue.
