The correct answer is 2.obstructive pulmonary disease COPD. COPD is a condition that has no cure and generally worsens over time. In the condition, there is poor airflow in the lungs caused by breakdown of lung tissue – an irreversible condition. The lungs of a person with COPD tend to trap air rather than breathe it in and out, causing difficulty breathing. Asthma tends to improve over time. Emphysema is an older term for COPD and used to describe the condition of the lung. Diabetes stroke is not a lung problem.
