Identify the wrong statement with reference to transport of oxygen.
A Partial pressure of $CO_2$ can interfere with $O_2$ binding with haemoglobin.
B Higher $H^+$ conc. in alveoli favours the formation of oxyhaemoglobin.
C Low $pCO_2$ in alveoli favours the formation of oxyhaemoglobin.
D Binding of oxygen with haemoglobin is mainly related to partial pressure of $O_2$.
