Emphysema and its effects on respiratory surface area:
Emphysema is a chronic respiratory disorder characterized by the damage to the walls of the alveoli in the lungs. This damage leads to a number of adverse effects on the respiratory system.

Decrease in respiratory surface area:
- The alveoli are responsible for the exchange of oxygen and carbon dioxide in the lungs.
- When the walls of the alveoli are damaged in emphysema, the surface area available for gas exchange is significantly reduced.
- This decrease in respiratory surface area impairs the ability of the lungs to efficiently exchange gases, leading to symptoms such as shortness of breath and reduced exercise tolerance.
Therefore, the correct answer is:

Option C) Respiratory surface area decreases
