The correct option is D In spermiogenesis spermatozoa are formed, while in spermiation spermatozoa are formed released from sertoli cells in to the cavity of seminiferous tubules
Spermatogenesis and spermiogenesis are two stages that occur during the formation of sperms.
Spermiogenesis is the process of maturation of spermatids into spermatozoa or sperm cells.
Spermiation is the process by which mature sperms are released from sertoli cells into the seminiferous tubule lumen prior to their passage to the epididymis.
