Identify the incorrect statement regarding the transport of oxygen:

• A
  The binding of oxygen with hemoglobin is primarily related to the partial pressure of $O_2$.
• B
  The partial pressure of $CO_2$ interferes with the binding of $O_2$ with hemoglobin.
• C
  High concentration of $H^+$ in the alveoli helps in the formation of oxyhemoglobin.
• D
  Low $P_{CO_2}$ in the alveoli helps in the formation of oxyhemoglobin.
