Systematics involves

Options

A. identification of organisms
B. relationships and classification of organisms
C. taxonomy of organisms
D. All of the above

Answer

**Step-by-Step Solution:**

1. **Understanding Systematics**:
- Systematics is the scientific study that focuses on the identification, classification, and naming of organisms. It encompasses various aspects of biology that help in organizing and categorizing living beings.

2. **Components of Systematics**:
- **Identification**: This involves recognizing and naming organisms based on their characteristics.
- **Classification**: This is the process of arranging organisms into groups based on shared characteristics.
- **Nomenclature**: This refers to the system of naming organisms, ensuring that each organism has a unique and universally accepted name.
- **Taxonomy**: This is the science of classification, which includes the naming and categorization of organisms based on their evolutionary relationships.

3. **Importance of Systematics**:
- Studying systematics helps us understand the evolutionary or phylogenetic relationships among organisms. This understanding is crucial for the classification of organisms and makes the study of biology more manageable.

4. **Evaluating the Statements**:
- **Statement 1**: Identification of organisms - This is a correct aspect of systematics.
- **Statement 2**: Relationships and classification of organisms - This is also correct, as systematics involves classification.
- **Statement 3**: Taxonomy of organisms - This is correct as well, since systematics includes taxonomy.

5. **Conclusion**:
- Since all the statements provided are correct regarding systematics, the answer to the question is option D: all of the above.

**Final Answer**: D) All of the above.
