Solution

The correct option is D Both A and C
According to Bohr's effect when the pH of blood increase near the lungs due to the presence of less carbon dioxide it increases the affinity of haemoglobin to bind with oxygen while near cells the carbon dioxide concentration is high which reduces the pH of blood and it decreases the affinity of oxygen to haemoglobin.
So the correct option is 'Both A and C'.
