Answer

To determine the pathway that sperm takes through the male reproductive system, we will analyze the sequence of structures it passes through. Here’s the step-by-step breakdown:

1. **Seminiferous Tubules (a)**: Sperm production begins in the seminiferous tubules, which are located within the testes. This is where spermatogenesis occurs.

2. **Rete Testis (d)**: After the sperm is produced in the seminiferous tubules, it moves into the rete testis, a network of tubules that collect sperm from the seminiferous tubules.

3. **Vasa Efferentia (e)**: From the rete testis, sperm travels through the vasa efferentia, which are small ducts that carry sperm from the rete testis to the epididymis.

4. **Epididymis (b)**: The sperm then enters the epididymis, where it matures and is stored until ejaculation.

5. **Vas Deferens (g)**: During ejaculation, sperm moves from the epididymis into the vas deferens, a muscular tube that transports sperm to the ejaculatory duct.

6. **Ejaculatory Duct (f)**: The vas deferens joins with the duct from the seminal vesicle to form the ejaculatory duct, which carries sperm into the urethra.

7. **Urethra (c)**: Finally, sperm is expelled from the body through the urethra, which is the final passage for sperm and urine.

Thus, the correct sequence of structures that sperm passes through is:
**Seminiferous Tubules (a) → Rete Testis (d) → Vasa Efferentia (e) → Epididymis (b) → Vas Deferens (g) → Ejaculatory Duct (f) → Urethra (c)**.
