Which among organism reproduces by the process of regeneration?

Options

A. Flatworm
B. Rhizopus
C. Plasmodium
D. Yeast

Explanation

**Step-by-Step Solution:**

1. **Understanding Regeneration**: Regeneration is a form of asexual reproduction where an organism can regrow lost body parts or even reproduce from a fragment of its body. This process is common in certain organisms.

2. **Analyzing the Options**:
- **Flatworm**: Flatworms are known for their remarkable ability to regenerate. If a flatworm is cut into pieces, each piece can develop into a new flatworm.
- **Rhizopus**: Rhizopus is a type of fungus that reproduces through spore formation, not regeneration.
- **Plasmodium**: Plasmodium is a protozoan that causes malaria and reproduces through multiple fission, which is also not regeneration.
- **Yeast**: Yeast is a unicellular fungus that reproduces through budding, which is a different method than regeneration.

3. **Conclusion**: Among the options provided, the organism that reproduces by the process of regeneration is the flatworm.

**Final Answer**: The organism that reproduces by the process of regeneration is the **flatworm**.
