Solution

The correct option is B Decreasing $O_{2}$ concentration in blood
Carbon dioxide is transported to the lungs either dissolved in plasma (5%), bound to proteins and haemoglobin in particular (10%) or combines with water as carbonic acid (85%). While haemoglobin can easily carry O $_{2}$ in it, while transporting CO $_{2}$ , it forms the compound carbaminohemoglobin which lowers the haemoglobin's affinity for oxygen. The combination of CO $_{2}$ with haemoglobin in the lungs can thus be promoted by Haldane effect as deoxygenation (decreasing of oxygen) of the blood increases its ability to carry carbon dioxide.
Therefore, the correct answer is option C.
