B. Seminiferous tubules - retetestis - vasa efferentia -epididymis - vasdeferens - urethra
C. Seminiferous tubules - seminal vesicles - vasa efferentia - epididymis - vasdeferens.
D. Seminal vesicles - vasdeferens - vasa efferentia - epididymis - retetestis

Answer

To determine the correct flow of sperm, we need to understand the anatomical structures involved in the male reproductive system and the sequence in which sperm travels from production to ejaculation. Here's a step-by-step solution:

### Step-by-Step Solution:

1. **Sperm Production**: Sperm is produced in the **seminiferous tubules** located within the testes. This is the starting point of sperm flow.

2. **Rete Testis**: After production, sperm moves into the **rete testis**, a network of tubules that collects sperm from the seminiferous tubules.

3. **Vasa Efferentia**: From the rete testis, sperm travels through the **vasa efferentia**, which are small ducts that lead to the epididymis.

4. **Epididymis**: The sperm then enters the **epididymis**, where it matures and is stored.

5. **Vas Deferens**: After maturation, sperm moves into the **vas deferens**. This duct transports sperm from the epididymis to the ejaculatory duct.

6. **Ejaculatory Duct**: The vas deferens joins with the duct from the seminal vesicle to form the **ejaculatory duct**, which passes through the prostate gland.

7. **Urethra**: Finally, the sperm enters the **urethra**, where it is expelled from the body during ejaculation.

### Correct Sequence of Sperm Flow:
The correct sequence of sperm flow is:
- Seminiferous tubules → Rete testis → Vasa efferentia → Epididymis → Vas deferens → Ejaculatory duct → Urethra

### Conclusion:
Based on the sequences provided in the question, the correct flow of sperm is represented by the sequence:
- **Seminiferous tubules → Rete testis → Vasa efferentia → Epididymis → Vas deferens → Urethra**

### Answer:
The correct answer is **Option B**.
