Options

A. Labia minora
B. fimbriae
C. infundibulum
D. isthmus

Answer

To identify the odd one out from the given options: Labia Minora, Fimbrae, Infundibulum, and Isthmus, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Options**:
- Labia Minora: This is part of the external genitalia in females.
- Fimbrae: These are finger-like projections at the end of the infundibulum of the oviduct that help in the collection of the ovum.
- Infundibulum: This is the funnel-shaped opening of the oviduct that is located near the ovary.
- Isthmus: This is the narrow part of the oviduct that connects to the uterus.

2. **Categorize the Options**:
- Fimbrae, Infundibulum, and Isthmus are all parts of the oviduct (fallopian tube) which is involved in the reproductive process.
- Labia Minora, on the other hand, is not part of the internal reproductive system but is part of the external genitalia.

3. **Identify the Odd One Out**:
- Since Labia Minora is the only option that is not part of the oviduct and is instead part of the external genitalia, it is the odd one out.

4. **Conclusion**:
- Therefore, the odd one from the options provided is **Labia Minora**.

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