Match List I with List II :  Choose the correct answer from the options given below :

Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R. Assertion A: During the transportation of gases, about $20-25$ percent of $\mathrm{CO}_2$ is carried by Haemoglobin as carbamino-haemoglobin. Reason R: This binding is related to high $\mathrm{pCO}_2$ and low $\mathrm{pO}_2$ in tissues. In the light of the above statements, choose the correct answer from the options given below.

Which of the following factors are favourable for the formation of oxyhaemoglobin in alveoli?

Vital capacity of lung is ______ .

Select the sequence of steps in Respiration. (A) Diffusion of gases $\left(\mathrm{O}_2\right.$ and $\left.\mathrm{CO}_2\right)$ across alveolar membrane. (B) Diffusion of $\mathrm{O}_2$ and $\mathrm{CO}_2$ between blood and tissues. (C) Transport of gases by the blood. (D) Pulmonary ventilation by which atmospheric air is drawn in and $\mathrm{CO}_2$ rich alveolar air is released out. (E) Utilisation of $\mathrm{O}_2$ by the cells for catabolic reactions and resultant release of $\mathrm{CO}_2$. Choose the correct answer from the options given below :
