Each segment of taenia is

Options

A. monoecius
B. Dioecius
C. Asexual
D. None of the above

Answer

To answer the question "Each segment of taenia is," we need to analyze the options provided and understand the reproductive structure of the Taenia, which is a genus of parasitic flatworms commonly known as tapeworms.

### Step-by-Step Solution:

1. **Understanding Taenia Segments**:
- Taenia is composed of segments called proglottids. Each proglottid can contain reproductive organs.

2. **Identifying the Reproductive Structure**:
- Each segment (proglottid) of Taenia contains both male and female reproductive organs. This means that each segment can produce both sperm and eggs.

3. **Determining the Correct Term**:
- The term that describes an organism or structure that has both male and female reproductive parts is "monaceous" (also known as hermaphroditic).

4. **Evaluating Other Options**:
- **Dioecious**: This term refers to organisms that have separate male and female individuals. This does not apply to Taenia segments.
- **Asexual**: This term indicates the absence of male and female reproductive parts, which is also incorrect for Taenia segments.
- **None of the above**: Since we have identified that Taenia segments are monaceous, this option is also incorrect.

5. **Conclusion**:
- Since each segment of Taenia has both male and female reproductive structures, the correct answer is that each segment of Taenia is **monaceous**.

### Final Answer:
Each segment of Taenia is **monaceous**.
