Options

A. Rate testis
B. Vasa efferentia
C. Fallopian tube
D. Epididymis

Answer

To determine which of the following is not an accessory duct of the male reproductive system, let's analyze the options provided.

### Step-by-Step Solution:

1. **Understand the Male Reproductive System**: The male reproductive system includes various structures that are responsible for the production, storage, and transportation of sperm.

2. **Identify Accessory Ducts**: The accessory ducts in the male reproductive system include:
- **Retetestis**: This is a network of tubules where sperm mature and are stored.
- **Epididymis**: This is a coiled tube where sperm mature and are stored before being transported.
- **Vas Deferens**: This duct transports sperm from the epididymis to the ejaculatory duct.
- **Urethra**: This duct carries sperm out of the body during ejaculation.

3. **Examine the Options**: The question asks which option is not an accessory duct of the male reproductive system.
- **Retetestis**: Accessory duct (correct).
- **Epididymis**: Accessory duct (correct).
- **Vas Deferens**: Accessory duct (correct).
- **Fallopian Tube**: This is part of the female reproductive system and is not an accessory duct for males.

4. **Conclusion**: The structure that is not an accessory duct of the male reproductive system is the **Fallopian Tube**.

### Final Answer:
The correct answer is **Fallopian Tube**.
