The question lacks options, the options are:

A. testicle B. epididymis C. penis D. vas deferens

The answer is Testicles or testes

Explanation:

Testis (plural-testes) is the male reproductive organ. It is responsible for producing the male sex cell or gamete. Sperm cells are produced by the division and differentiation of germ cells (a process called spermatogenesis) located in the seminiferous tubules, which is a tube-like structure located in the testicles. The testes is responsible for secreting the hormone, TESTOSTERONE, that catalyzes this process.

This sperm cell produced are still immature. They undergo development until maturity when they travel to another region of the testes called EPIDIDYMIS. Matured sperm cells finally leave the epididymis and becomes stored in the VAS DEFERENS, from where they mix with seminal fluid to form SEMEN and released from the male's penis.
