| 1. | Systematics is a broader field that includes taxonomy, focusing on the evolutionary relationships between organisms, while taxonomy specifically deals with the classification, identification, and naming of organisms. |
| 2. | Taxonomy is a broader field that includes systematics, which focuses solely on the genetic differences between species. |
| 3. | Systematics and taxonomy are completely independent fields with no overlap in their objectives. |
| 4. | Systematics is only concerned with the physical characteristics of organisms, while taxonomy includes both physical and genetic traits. |
| Statement I: | The process of naming organisms according to a universally accepted system is known as nomenclature. |
| Statement II: | Nomenclature can be applied without the need for proper identification of the organism. |
| 1. | Only Statement I is correct |

| 3. | Both Statement I and Statement II are correct |
| 4. | Neither Statement I nor Statement II is correct |
| Statement I: | Species is the lowest taxonomic category in the hierarchy. |
