The branch dealing with classification is

Options

A. Genetics
B. Ecology
C. Taxonomy
D. Nomenclature.

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the branch of biology that deals with classification. Classification is the process of organizing living organisms into categories based on shared characteristics.

2. **Identifying Relevant Branches**: In biology, there are several branches that deal with different aspects of life sciences. The main branches include:
- Taxonomy
- Genetics
- Ecology
- Nomenclature

3. **Analyzing Each Option**:
- **Taxonomy**: This is the branch of biology that specifically deals with the classification of living organisms. It involves grouping organisms based on similarities and differences, and it also includes naming these organisms.
- **Genetics**: This branch focuses on heredity and the variation of traits among organisms. It does not primarily deal with classification.
- **Ecology**: This branch studies the interactions between organisms and their environment. It is not focused on classification.
- **Nomenclature**: This refers to the system of naming organisms. While it is related to classification, it does not encompass the entire process of classification itself.

4. **Conclusion**: Based on the analysis, the correct answer to the question is **Taxonomy** (Option C), as it is the branch that deals specifically with the classification of living organisms.

**Final Answer**: The branch dealing with classification is **Taxonomy**.
