Which one among the following is an example for homology ?

Options

A. Eye of octopus and mammals
B. Tuber of sweet potato and potato
C. Wings of butterfly and dolphins
D. Thorn and tendrils of Bougainvillea and Cucurbita

Answer

To answer the question "Which one among the following is an example for homology?", we need to understand the concept of homology in the context of biology and evolution.

### Step-by-Step Solution:

1. **Define Homology**: Homology refers to the similarity in structure or function between different species that arises from a common ancestor. This can be seen in anatomical structures, genetic sequences, or developmental processes.

2. **Identify Examples of Homologous Structures**: Common examples of homologous structures include:
- The forelimbs of mammals (like humans, whales, and bats) which have different functions but share a similar underlying skeletal structure.
- The wings of birds and the forelimbs of reptiles, which also have a common structural origin.

3. **Evaluate the Options**: If provided with multiple choices, we would need to evaluate each option to determine which one represents a homologous structure.
- Look for structures that have a similar anatomical framework but may serve different purposes in different species.

4. **Select the Correct Example**: Once you identify the option that demonstrates the concept of homology, that would be your answer.

### Conclusion:
The correct answer would be the option that illustrates a structural similarity due to common ancestry, such as the forelimbs of mammals.
