Answer: The correct answer is- testes → epididymis → vas deferens → urethra.
Sperms are the male reproductive cells that are produced during spermatogenesis ( process of gamete formation in males).
Sperms are produced in seminiferous tubule ( that lie within testes) and the they migrate to epididymis ( where they are stored and matured). Sperms travel from epididymis to a muscular tube that is called vas deferens. Finally, sperms are propelled towards urethra via ejaculatory duct.
