Final Answer :
A
Explanation :
The PO2 code refers to the partial pressure of oxygen (PO2) in different parts of the body. In alveolar air, the PO2 is higher than in venous blood, because oxygen is taken up from the alveoli into the blood and transported to tissues, where it is used for cellular respiration, leading to a lower PO2 in venous blood returning to the lungs.
