The correct answer is Emphysema.

Emphysema is a progressive and irreversible lung disease in which the alveoli, the tiny air sacs in the lungs, are damaged and destroyed. This can lead to shortness of breath, wheezing, coughing, and fatigue. Emphysema is a common type of COPD (chronic obstructive pulmonary disease), which also includes chronic bronchitis.

Emphysema is caused by a combination of factors, including smoking, genetics, and exposure to air pollution. Although emphysema cannot be reversed, there are treatments available to help manage the symptoms and slow down the progression of the disease.
