Where do sperms get matured?
a)	In seminal vesicle	b)	Seminiferous tubules
c)	In epididymis	d)	Vasa efferentia

(a)

Epididymis is a mass of coiled tubules attached to the posterior surface of the testes. It stores the sperms temporarily. Sperms achieve maturity and motility in epididymis by reabsorption of fluid secreted originally by the seminiferous tubules and by chemicals produced by the lining of epididymal tube.
