| Assertion (A): | Smoking increases the carbon monoxide (CO) content in the blood which has a greater affinity to hemoglobin than oxygen. |
| Reason (R): | CO forms a stable bond with haemoglobin and does not allow the binding of oxygen. It reduces the concentration of heme bounded oxygen and causes oxygen deficiency in the body. |
| 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. | (A) is false but (R) is true. |
