Identify the odd one from the following.

Options

A. Labia minora
B. Fimbriae
C. lnfundibulum
D. Isthmus

Answer

To identify the odd one out from the given options, we need to analyze each option in relation to the others.

### Step-by-Step Solution:

1. **Understand the Options**:
- We have four terms: Labia Minora, Infundibulum, Ampulla, and Isthmus.

2. **Define Each Term**:
- **Labia Minora**: This is a part of the female external genitalia, located inside the labia majora. It is not part of the reproductive tract but rather part of the vulva.
- **Infundibulum**: This is a part of the fallopian tube, which is involved in the transport of the egg from the ovary to the uterus.
- **Ampulla**: This is another section of the fallopian tube, typically where fertilization occurs.
- **Isthmus**: This is the narrow part of the fallopian tube that connects to the uterus.

3. **Identify the Commonality**:
- The Infundibulum, Ampulla, and Isthmus are all parts of the fallopian tube, which is part of the internal reproductive system in females.
- In contrast, the Labia Minora is part of the external genitalia and does not belong to the internal reproductive structures.

4. **Conclusion**:
- Since Labia Minora is the only option that does not belong to the fallopian tube or the internal reproductive system, it is the odd one out.

### Final Answer:
- The odd one out is **Labia Minora**.
