Given below is a list of different steps (i-vi) involved in respiration.
(i) Utilisation of `O_(2)` by the cells for cataolic reactions.
(ii) Transport of gases by the blood.
(iii) Pulmonary ventilation by which atmospheric air is drawn in and `CO_(2)` is released out.
(iv) Release of resultant `CO_(2)`.
(v) Diffusion of `O_(2)` and `CO_(2)` between blood and tissues.
(vi) Diffusion of gases (`O_(2)` and `CO_(2)`) across alveolar tissues.
Select an option which has correct sequence of all the steps.
