Taxonomy comprises

Options

A. Identification
B. Classification
C. Nomenclature
D. All of these

Answer

**Step-by-Step Solution:**

1. **Understanding Taxonomy**: Taxonomy is a branch of science that deals with the naming, describing, and classifying of organisms. It is essential for organizing the vast diversity of life on Earth.

2. **Identification**: The first step in taxonomy is identification. This involves recognizing and matching an organism with previously described organisms based on its characteristics.

3. **Nomenclature**: After identification, the next step is nomenclature, which is the process of assigning a proper name to the identified organism. This name allows for universal recognition and communication about the organism.

4. **Classification**: The final step is classification, where organisms are grouped based on their similarities and differences. This helps in organizing organisms into categories or classes.

5. **Conclusion**: Since taxonomy encompasses all three processes—identification, nomenclature, and classification—the correct answer to the question is "all of these."

**Final Answer**: Taxonomy comprises identification, classification, nomenclature, and all of these.
