Inter-breeding animals belong to the same

Options

A. (a) genus
B. (b) family
C. (c) species
D. (d) order

Answer

To answer the question "Inter-breeding animals belong to the same:", we need to analyze the options provided and understand the biological classification system.

### Step-by-Step Solution:

1. **Understanding Inter-breeding**:
- Inter-breeding refers to the ability of organisms to mate and produce offspring. For animals to inter-breed successfully, they must belong to the same group.

2. **Analyzing the Options**:
- **A) Genus**: This is a higher taxonomic rank that includes one or more species. While species within a genus can inter-breed, not all members of a genus can.
- **B) Family**: This is a broader classification that includes multiple genera. Members of different genera within a family may not be able to inter-breed.
- **C) Species**: This is the most specific classification. Members of the same species can inter-breed and produce viable and fertile offspring.
- **D) Order**: This is an even broader classification that includes multiple families. Members of different families within an order cannot inter-breed.

3. **Defining Species**:
- The biological concept of species states that a species is a group of organisms that can potentially interbreed and produce viable and fertile offspring. This definition emphasizes the reproductive isolation from other groups.

4. **Conclusion**:
- Based on the definitions and classifications, the correct answer is **C) Species**. Inter-breeding animals belong to the same species.

### Final Answer:
C) Species
