Solution
The correct option is D Emphysema
Emphysema is included in a group of diseases called chronic obstructive pulmonary disease or COPD (here, pulmonary refers to the lungs). Emphysema is called an obstructive lung disease because airflow on exhalation is slowed or stopped because over-inflated alveoli do not exchange gases when a person breaths due to little or no movement of gases out of the alveoli. Tobacco smoke also damages the air sacs in the lungs. Over time this leads to progressive loss of lung function and condition emphysema. Smoking causes 82% of emphysema chronic bronchitis among males and 76% among females.
So, the correct answer is option D.
