Arrange the given steps of the respiration mechanism in the order they occur in the human body:
$I.$ Breathing or pulmonary ventilation
$II.$ Diffusion of $O_2$ and $CO_2$ between blood and tissues
$III.$ Transport of gases by blood
$IV.$ Utilisation of $O_2$ by cells
$V.$ Diffusion of $O_2$ and $CO_2$ across the alveolar membrane
Choose the correct option.

• A
  $I \rightarrow II \rightarrow III \rightarrow IV \rightarrow V$
• B
  $I \rightarrow IV \rightarrow III \rightarrow V \rightarrow II$
• C
  $I \rightarrow V \rightarrow III \rightarrow II \rightarrow IV$
• D
  $I \rightarrow III \rightarrow II \rightarrow IV \rightarrow V$
