Asthma is characterized by wheezing and breathing difficulties resulting from inflammation of the bronchi and bronchioles. On the other hand, emphysema is a chronic condition that leads to abnormal distension of the bronchioles or alveolar sacs in the lungs, resulting in a decreased respiratory surface area for oxygen and carbon dioxide exchange. Hence, the correct answer is option 1.
