inhaled air contains more oxygen than exhaled air.
inhaled air does not pass directly from the trachea to the alveoli, it must pass through the bronchi and bronchioles first.
exhaled air contains more carbon dioxide than oxygen.
neither inhaled nor exhaled air passes through the diaphragm. the diaphragm is a large muscle situated below the lungs.

Letter A. It's oxygen in the air that we need during inhaling to keep us breathing. Of course exhaled air are already carbon dioxide.
