Identify the wrong statement with reference to transport of oxygen.

• A

  Partial pressure of ${\mathrm{CO}}_2$ can interfere with ${\mathrm{O}}_2$ binding with haemoglobin.

• B

  Higher ${\mathrm{H}}^{+}$ conc. in alveoli favours the formation of oxyhaemoglobin.

• C

  Low ${\mathrm{pCO}}_2$ in alveoli favours the formation of oxyhaemoglobin.

• D

  Binding of oxygen with haemoglobin is mainly related to partial pressure of ${\mathrm{O}}_2$.
