Regeneration of liver is

Options

A. Metamorphosis
B. Reparative regeneration
C. Epimorphosis
D. Morphogenesis

Answer

### Step-by-Step Solution:

1. **Understanding Regeneration**: Regeneration refers to the process of re-formation or regrowth of lost body parts or organisms. The prefix "re-" means again, and "generation" refers to formation.

2. **Types of Regeneration**: There are two main types of regeneration:
- **Epimorphosis**: This type involves the reconstruction or reformation of a missing part of the body. It typically occurs in organisms where specific body parts can regrow.
- **Morpholaxis**: This type involves the reorganization of the remaining parts of the body. A small piece can develop into an entire organism.

3. **Examples of Regeneration**:
- **Epimorphosis Example**: The regeneration of a lizard's tail is a classic example where the missing part (tail) is reconstructed.
- **Morpholaxis Example**: In hydra, if it is cut into pieces, each piece can develop into a new hydra, demonstrating morpholactic regeneration.

4. **Regeneration of the Liver**: The question specifically asks about the regeneration of the liver. In this case, liver cells divide and proliferate to form more liver cells. This process does not involve the reorganization of existing structures but rather the multiplication of cells.

5. **Conclusion**: Since the regeneration of the liver involves the proliferation of liver cells without reorganization, it is classified as **epimorphosis**.

### Final Answer:
The regeneration of the liver is an example of **epimorphosis**.
