Solution
The correct option is C Epididymis, vas deferens, ampulla of vas deferens, ejaculatory duct, urethra The correct pathway in which the sperm travels is given below:
The sperms are produced in the seminiferous tubules of the testes
From seminiferous tubules, they travel to the vasa efferentia through rete testis
From the vasa efferentia, they travel to the epididymis
From epididymis, they travel to the vas deferens. Vas deferens unites with the ducts of the seminal vesicles and they form ejaculatory duct
The ejaculatory duct passes through the prostrate and the contents ultimately get emptied into the urethra
Therefore, option (c) is the correct option which shows the correct pathway of the sperm during the process of ejaculation.
Epididymis -> vas deferens -> ampulla of vas deferens -> ejaculatory duct -> urethra
