Hand of man, wing of bat and flipper of seal represent `:`

Options

A. Analogous organs
B. Vestigial organs
C. Homologous organs
D. Evolutionary organs.

Answer

To solve the question regarding the relationship between the hand of man, the wing of a bat, and the flipper of a seal, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Structures**: We are given three structures: the hand of man, the wing of a bat, and the flipper of a seal.

2. **Analyze the Similarities**: All three structures share a similar basic structural plan. They are composed of the same set of bones, which include the humerus, radius, ulna, carpals, and metacarpals.

3. **Understand the Functionality**: Although these structures have a similar anatomical structure, they serve different functions. The hand is used for manipulation, the wing is used for flying, and the flipper is used for swimming.

4. **Define the Terms**:
- **Analogous Organs**: Organs that perform similar functions but have different evolutionary origins.
- **Vestigial Organs**: Organs that have lost most or all of their original function through evolution.
- **Homologous Organs**: Organs that have a similar basic structure and embryonic origin but may serve different functions.
- **Evolutionary Organs**: This term is not commonly used in biological classification.

5. **Conclusion**: Since the hand of man, the wing of a bat, and the flipper of a seal have a similar structural design and different functions, they are classified as homologous organs.

### Final Answer:
The hand of man, wing of bat, and flipper of seal represent **homologous organs**.
