During respiration, oxygen and carbon dioxide are exchanged in the alveoli of the lungs. Oxygen from the inhaled air diffuses across the walls of the alveoli and into the surrounding capillaries, while carbon dioxide from the capillaries diffuses across the walls of the alveoli and into the air in the lungs. The exchange of oxygen and carbon dioxide in the alveoli is critical for the uptake of oxygen by the body and the removal of carbon dioxide from the body. Therefore, the correct answer is option 1 which is Oxygen, as it is the gas that is exchanged in the alveoli during respiration.
