Hint: Emphysema is a long-term, chronic lung illness or disease that primarily causes shortness of breath due to alveolar over swelling (air sacs in the lung). The internal dividers of the air sacs weaken and break over time, resulting in larger air spaces rather than numerous small ones.

Complete answer:
Emphysema slowly harms the air sacs (alveoli) in your lungs, making you continuously more winded. Emphysema is one of a few infections referred to on the whole as persistent obstructive respiratory illness (COPD). Smoking is the main source of emphysema.
Your lungs' alveoli are grouped like lots of grapes. In emphysema, the internal dividers of the air sacs debilitate and ultimately break — making one bigger air space rather than numerous little ones. This decreases the surface space of the lungs and, thus, the measure of oxygen that arrives at your circulatory system. At the point when you breathe out, the harmed alveoli don't work as expected and old air gets caught, ruling out new, oxygen-rich air to enter. Treatment may moderate the movement of emphysema; however, it can't switch the harm.

Accordingly, the right answer is alternative A) Cigarette smoking

Note:
The vast majority with emphysema additionally have ongoing bronchitis. Ongoing bronchitis is aggravation of the cylinders that convey air to your lungs (bronchial cylinders), which prompts a steady cough. Emphysema and constant bronchitis are two conditions that make up persistent obstructive respiratory illness (COPD). Smoking is the main source of COPD. Treatment may moderate the movement of COPD.
