Consider the given two statements:
| Assertion (A): | The genes encoding resistance to antibiotics such as ampicillin, chloramphenicol, tetracycline or kanamycin, etc., are considered useful selectable markers for E. coli. |
| Reason (R): | The normal E. coli cells do not carry resistance against any of these antibiotics. |
| 1. | Both (A) and (R) are True and (R) correctly explains (A). |
| 2. | (A) is True; (R) is False |
| 3. | (A) is False; (R) is False |
| 4. | Both (A) and (R) are True but (R) does not correctly explain (A). |
