Solution

The correct option is A pH is around 6
Most of the oxygen transported is bound to hemoglobin. Hemoglobin binds oxygen to form oxyhemoglobin. In lung alveoli, oxygen combines with hemoglobin to form oxyhemoglobin. The conditions favourable for formation of hemoglobin are high partial pressure of oxygen, low partial pressure of carbon dioxide, low concentration of protons, low temperature.
Therefore, the correct answer is option A.
