| Assertion (A): | Deoxyribose, , is not a carbohydrate. |
| Reason (R): | Carbohydrates are hydrates of carbon so compounds that follow the formula are carbohydrates. |
| 1. | (A) and (R) both are correct statements and (R) explain the (A). |
| 2. | Both (A) and (R) are wrong statements. |
| 3. | (A) is the correct statement and (R) is the wrong statement. |
| 4. | (A) is the wrong statement and (R) is the correct statement. |
