2. **Evaluating the Options**:
- **Option 1: Earthworm**
- Earthworms are indeed hermaphrodites. They have both male and female reproductive organs, allowing them to mate with any other earthworm.
- **Conclusion**: This option is incorrect for the question.

- **Option 2: Leech**
- Leeches are also hermaphrodites. They possess both reproductive organs and can reproduce with any other leech.
- **Conclusion**: This option is incorrect for the question.

- **Option 3: Tinea (Tapeworm)**
