Species having exclusive areas of the geographic distribution are

Options

A. sibling species
B. morphospecies
C. sympatric species
D. allopathic species

Answer

To solve the question "Species having exclusive areas of geographic distribution are," we need to analyze the given options and determine which one fits the description best.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for species that have exclusive geographic distributions. This means we are looking for species that are not found in overlapping areas with other species.

2. **Analyzing the Options**:
- **Sibling Species**: These are species that are genetically very similar and often live in the same geographic area. They do not have exclusive distributions, so this option is incorrect.
- **Morphospecies**: This term refers to species defined by morphological characteristics. While they may differ in appearance, they can still share geographic ranges. Therefore, this option is also incorrect.
- **Sympatric Species**: These species live in the same geographic area and can have overlapping distributions. They evolve from a common ancestor and are not exclusive to specific areas, making this option incorrect as well.
- **Allopatric Species**: These species are geographically separated from each other due to physical barriers (like mountains, rivers, etc.). This separation leads to exclusive areas of distribution, making this option the correct choice.

3. **Conclusion**: After analyzing all the options, the correct answer to the question is **Allopatric Species**.

### Final Answer:
**Allopatric Species**
