Find the odd one out

Options

A. Trunk of an elephants and hand of a chimpanzee
B. Ginner and sweet potato
C. Wings of bat and insect
D. Nails of human beings and claws of a cat

Answer

To solve the question "Find the odd one out," we will analyze the given options based on the concepts of analogous and homologous organs in biology.

### Step-by-Step Solution:

1. **Identify the Options:**
- Option 1: Trunk of an elephant and hand of a chimpanzee.
- Option 2: Ginger and sweet potato.
- Option 3: Wings of a bat and wings of insects.
- Option 4: Nails of human beings and claws of a cat.

2. **Analyze Option 1:**
- The trunk of an elephant and the hand of a chimpanzee have different origins but serve the same function (grasping and manipulating objects).
- Conclusion: They are analogous organs.

3. **Analyze Option 2:**
- Ginger (a stem modification) and sweet potato (a root modification) also have different origins but serve the same function (food storage).
- Conclusion: They are analogous organs.

4. **Analyze Option 3:**
- The wings of a bat and the wings of insects have different origins but serve the same function (flying).
- Conclusion: They are analogous organs.

5. **Analyze Option 4:**
- The nails of human beings and the claws of a cat have the same origin (both are derived from the skin) but serve different functions (nails for manipulation and claws for catching prey).
- Conclusion: They are homologous organs.

6. **Determine the Odd One Out:**
- Options 1, 2, and 3 are all examples of analogous organs (different origins, same function).
- Option 4 is an example of homologous organs (same origin, different function).
- Therefore, the odd one out is **Option 4**.

### Final Answer:
**Option 4: Nails of human beings and claws of a cat is the odd one out.**
