Answer:
A. Stores sperm cells until they mature
Step-by-step explanation:
Epididymis is a coiled tube like structure present at the top of the testes. Sperms are produced in seminiferous tubules of testes through the process of spermatogenesis. Sperms are delivered to epididymis from testes for storage. Sperms are matured and become capable of fertilizing egg cell in epididymis. Maturation of sperms refers to acquiring the ability of fertilization in epididymis.
