Which one of the following obligate category in taxonomic hierachy will have maximum number of common characters?

Options

A. Family
B. Class
C. Order
D. Species

Answer

To solve the question about which obligate category in taxonomic hierarchy has the maximum number of common characters, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Taxonomic Hierarchy**:
- Taxonomic hierarchy is a system used to classify living organisms. The main categories in this hierarchy, from the broadest to the most specific, are: Kingdom, Phylum, Class, Order, Family, Genus, and Species.

2. **Identify the Categories Given**:
- The categories provided in the question are: Family, Class, Order, and Species.

3. **Determine Common Characters**:
- As we move from the broad categories (like Kingdom) to the more specific categories (like Species), the number of common characters among organisms decreases.
- For example, organisms in the same Kingdom may share very few specific traits, while organisms in the same Species share many specific traits.

4. **Analyze Each Category**:
- **Species**: This category has the most specific characteristics and thus the maximum number of common traits among its members.
- **Family**: Members share some common traits but are less specific than species.
- **Order**: Even broader, with fewer common traits than Family.
- **Class**: Broader still, with even fewer common traits.

5. **Conclusion**:
- Since Species represents the most specific level of classification, it will have the maximum number of common characters compared to Family, Class, and Order.

### Final Answer:
- The obligate category in taxonomic hierarchy that will have the maximum number of common characters is **Species**.
