Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R):
In the light of the above statements choose the correct answer from the options given below:
| Assertion (A): | The amount of carbon dioxide that can diffuse through the diffusion membrane per unit difference in partial pressure is much higher compared to that of oxygen. |
| Reason (R): | The solubility of carbon dioxide is 20 – 25 times lower than that of oxygen. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 3. | (A) is True but (R) is False. |
| 4. | Both (A) and (R) are False. |

Which of the following statements is not correct?
| 1. | Every 100 ml of oxygenated blood can deliver around 5 ml of oxygen to the tissue under normal physiological conditions. |
| 2. | Oxygen gas has most potent effect on the central chemoreceptors and plays most vital role in regulation of respiration |
| 3. | Nearly 70 percent of carbon dioxide is carried as bicarbonate in the blood. |
| 4. | Every 100 ml of deoxygenated blood delivers about 4 ml of carbon dioxide to the alveoli. |
