(D) The binding of $O_{2}$ with haemoglobin is a complex process influenced by several factors.Each haemoglobin molecule can carry a maximum of four molecules of $O_{2}$ as shown by the reaction: $Hb_{4} + 4O_{2} \rightarrow Hb_{4}O_{8}$.The dissociation of oxygen from oxyhaemoglobin is primarily related to the partial pressure of $O_{2}$ $(pO_{2})$,partial pressure of $CO_{2}$ $(pCO_{2})$,hydrogen ion concentration $(pH)$,and temperature.High $pO_{2}$,low $pCO_{2}$,low $H^{+}$ concentration,and lower temperature favor the formation of oxyhaemoglobin,whereas opposite conditions favor the dissociation of oxygen from the oxyhaemoglobin.Therefore,all four factors ($I, II, III,$ and $IV$) play a critical role in the binding and dissociation of oxygen with haemoglobin.

Binding of $O_{2}$ with haemoglobin is primarily dependent upon:
$I.$ Partial pressure of $O_{2}$
$II.$ Partial pressure of $CO_{2}$
$III.$ Hydrogen ion concentration
$IV.$ Temperature

$A$: $100 \; ml$ of venous blood contains $14.4 \; ml$ of $O_2$,meaning it is still $75\%$ saturated with oxygen under normal conditions.
$R$: About $4.6 \; ml$ of $O_2$,i.e.,$25\%$,diffuses from arterial blood into the tissues during resting conditions.
