The correct option is A Spermiation
During the production of sperms in the testes, the spermatids are transformed into spermatozoa (sperms) by the process called spermiogenesis. After spermiogenesis, mature spermatozoa are released from sertoli cells of the seminiferous tubules of testes by the process called spermiation. Semination is the process of deposition of sperms in the female genital tract. It can be natural or artificial, as in case of animal breeding procedures. Thus, the correct answer is option A.
