Which statement best describes COPD?

Explanation:
Understanding what COPD is. COPD is a chronic inflammatory disease of the lungs that causes damage to the airways and air sacs, leading to airflow limitation. It typically results from long-term exposure to irritants like tobacco smoke and brings symptoms such as breathlessness, chronic cough, and mucus production. The defining feature is damage and inflammation in the lungs, rather than heart, kidney, or brain disease, though COPD can raise cardiovascular risk as a consequence of reduced oxygenation.
