The largest taxon is

Options

A. Kingdom
B. Division
C. Phylum
D. Domain

Answer

**Step-by-Step Solution:**

1. **Understanding Taxon**: A taxon is a group of organisms that share similar characteristics. The classification of living organisms is organized into a hierarchy of taxonomic ranks.

2. **Hierarchy of Classification**: The hierarchy of classification includes the following ranks in order:
- Domain
- Kingdom
- Phylum (or Division)
- Class
- Order
- Family
- Genus
- Species

3. **Identifying the Largest Taxon**: To determine which taxon is the largest, we need to consider both the number of individuals it contains and the shared characteristics among organisms.
- The **Domain** is the highest rank in the hierarchy and contains the most number of individuals.
- As we move down the hierarchy (from Domain to Species), the number of individuals decreases.

4. **Conclusion**: Since the Domain contains the largest number of individuals compared to other taxonomic ranks, it is identified as the largest taxon.

5. **Final Answer**: The largest taxon is the **Domain**.
