Select the correct sequence for transport of sperm cells in male reproductive system.

• Seminiferous tubules → Rete testis → Vasa efferentia → Epididymis → Vas deferens → Ejaculatory duct → urethra → urethral meatus

• Seminiferous tubules → Vasa efferentia → epididymis → Inguinal canal → Urethra

• Testis → Epididymis → vasa efferentia → vas deferens → ejaculatory duct → inguinal canal → urethra → Urethral meatus

• Testis → Epididymis → Vasa efferentia → Rete testis → Inguinal canal → Urethra
