| Assertion (A): | The artificial systems used for classification of living organisms are not very acceptable to taxonomists. |
| Reason (R): | The artificial systems give more weightage to vegetative characteristics and no weightage to sexual characteristics and the sexual characteristics are easily affected by environment. |
| 1. | Both (A) and (R) are True and (R) correctly explains (A). |
| 2. | Both (A) and (R) are False. |
| 3. | (A) is True but (R) is False. |
| 4. | Both (A) and (R) are True but (R) does not correctly explain (A). |
| 1. | Artificial system | 2. | Natural system |
| 3. | Phylogenetic system | 4. | Useless system |
| I: | Phylogenetic classification systems are based on evolutionary relationships. |
| II: | Numerical Taxonomy is based on all observable characteristics. |
