Step-by-Step Solution
The complete worked solution.
Every step explained - no skipped algebra.
Emphysema is a chronic lung condition characterized by the destruction of the alveolar walls, which leads to:
Loss of alveolar surface area available for gas exchange
Decreased elastic recoil of the lungs (so decreased lung elasticity, not increased)
Impaired gas exchange
So the correct choice is decreased alveolar surface area.
Final Answer: Option B - Decreased alveolar surface area
