Final answer:
The epididymis is the site of sperm maturation and storage in the male reproductive system. It is a long, coiled tube that provides the environment for sperm to mature and gain the ability to move and to fertilize an egg.
Step-by-step explanation:
The correct answer to the question is B) Epididymis. The epididymis is a long, coiled tube that stores sperm and transports it from the testes. This organ plays a crucial role in sperm maturation, which can take several weeks. During this maturation process, sperm gain the ability to move and to fertilize an egg. The epididymis also serves as a reservoir for mature sperm waiting to be ejaculated. Other terms like spermatic cord, rete testis, seminiferous tubules, and vas deferens are all parts of the male reproductive system, but they do not store and mature sperm in the same way the epididymis does.
