In taxonomy the first step is :-

Options

A. Identification
B. Nomenclature
C. Classification
D. Affinities

Answer

**Step-by-Step Solution:**

1. **Understanding Taxonomy**: Taxonomy is the branch of science concerned with the classification of living organisms. It involves principles, rules, and procedures to categorize organisms based on their similarities and differences.

2. **Identifying the Steps in Taxonomy**: The process of taxonomy generally involves three main steps:
- Identification
- Nomenclature
- Classification

3. **First Step - Identification**: The very first step in taxonomy is Identification. This involves recognizing and determining the characteristics of an organism to establish what it is.

4. **Second Step - Nomenclature**: After identification, the next step is Nomenclature, which is the process of naming the identified organisms according to established rules.

5. **Third Step - Classification**: Finally, the last step is Classification, where organisms are grouped based on their similarities and differences identified during the previous steps.

6. **Conclusion**: Therefore, the first step in taxonomy is Identification.

**Final Answer**: Identification
