Options

A. Sympatric
B. Allopatric
C. Parapatric
D. Ring species

Answer

To answer the question "Species living in same or overlapping geographical areas are called," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the term used to describe species that inhabit the same or overlapping geographical areas.

2. **Identifying Key Terms**: The key terms here are "same" and "overlapping geographical areas." This indicates that we are looking for a specific type of species distribution.

3. **Exploring Relevant Terms**:
- **Sympatric Species**: This term refers to species that live in the same geographic area and can potentially interact with one another.
- **Allopatric Species**: This term refers to species that are geographically separated and do not overlap in their habitats.
- **Parapatric Species**: This term refers to species that are adjacent to each other but do not completely overlap in their habitats.
- **Ring Species**: This term refers to a situation where a series of neighboring populations can interbreed with their neighbors, but the populations at the ends of the series cannot interbreed.

4. **Selecting the Correct Term**: Since the question specifies "same or overlapping geographical areas," the correct term is **sympatric species**. These species coexist in the same area and can interact.

5. **Conclusion**: Therefore, the answer to the question is that species living in the same or overlapping geographical areas are called **sympatric species**.
