Animals are classified into hierarchical group, in which one of the following the largest number of species is found

Options

A. Genus
B. Order
C. Family
D. Cohort

Answer

To solve the question regarding the classification of animals and identifying which hierarchical group contains the largest number of species, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Hierarchical Classification**:
- Animals are classified into a hierarchy that includes several levels: Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species.

2. **Identify the Options**:
- The options given are: Genus, Order, Family, and Cohort.

3. **Analyze Each Option**:
- **Genus**: A genus is a group of species that are closely related. It is a lower taxonomic rank.
- **Family**: A family is a higher taxonomic rank that includes several genera (plural of genus).
- **Order**: An order is a higher taxonomic rank that includes several families.
- **Cohort**: This term is less commonly used in strict taxonomic classification and typically refers to a group of organisms that share a common characteristic, often within a species.

4. **Determine the Largest Group**:
- Among the options, the order is the highest taxonomic rank listed. It encompasses multiple families, which in turn include multiple genera and species. Therefore, it contains the largest number of species compared to the other options.

5. **Conclusion**:
- Based on the hierarchical classification, the group that contains the largest number of species is **Order**.

### Final Answer:
The correct answer is **Order**.
