The wings of bat and birds are :

Options

A. Homologous but not analogous
B. Neither homologous nor analogous
C. Analogous but not homologous
D. Vestigial.

Answer

To answer the question "The wings of bat and birds are:", we need to analyze the characteristics of the wings of bats and birds in terms of their evolutionary significance.

### Step-by-Step Solution:

1. **Identify the Structures**:
- The wings of bats and birds are both used for flying. However, they are structurally different. Bat wings are made of skin stretched over elongated fingers, while bird wings are made of feathers attached to a rigid bone structure.

2. **Determine the Type of Organs**:
- Despite their functional similarity (both are used for flight), the wings of bats and birds are not derived from a common ancestor in the same way. This means they evolved independently to serve the same function.

3. **Define Homologous Structures**:
- Homologous structures are those that have a similar origin but may serve different functions. In this case, the wings of bats and birds are not homologous because they do not share a common evolutionary origin.

4. **Define Analogous Structures**:
- The wings of bats and birds are considered analogous structures. Analogous structures are those that perform similar functions but have different evolutionary origins. This is a result of convergent evolution, where different species evolve similar traits independently.

5. **Conclusion**:
- Therefore, the wings of bats and birds are analogous organs, as they serve the same function (flight) but have different structural origins.

### Final Answer:
The wings of bats and birds are analogous organs.
