Options

A. Eye
B. Liver
C. Bone
D. Tail

Answer

To answer the question regarding which limb undergoes regeneration in autotomy, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Autotomy**:
- Autotomy is the process by which an organism can shed or discard its own appendages as a self-defense mechanism. This is often done to escape from predators.

2. **Identifying the Organisms**:
- Certain organisms, particularly some reptiles like lizards, exhibit autotomy. They can shed parts of their body, most commonly their tails, when threatened.

3. **Regeneration Capability**:
- After shedding an appendage, many organisms have the ability to regenerate that lost part. In the case of lizards, they can regenerate their tails after autotomy.

4. **Evaluating the Options**:
- **Eye**: Regeneration does not occur in the eye through autotomy.
- **Liver**: The liver can regenerate, but it does not involve autotomy.
- **Bone**: Bones do not regenerate through autotomy.
- **Tail**: Lizards can regenerate their tails after shedding them through autotomy.

5. **Conclusion**:
- Based on the understanding of autotomy and regeneration, the correct answer to the question is that regeneration occurs in the tail of lizards.

### Final Answer:
- The limb that undergoes regeneration in autotomy is the **tail**.
