The process through which spermatids are transformed into spermatozoa (sperms) is known as:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Spermiogenesis
Option (1) Spermatogenesis — Incorrect. Spermatogenesis is the whole process of sperm formation from spermatogonia.
Option (2) Spermiogenesis — Correct. Spermatids formed by meiosis are transformed into spermatozoa (sperms) by spermiogenesis. The sperm heads get embedded in Sertoli cells and are then released by spermiation.
Option (3) Spermiation — Incorrect. Spermiation is the release of sperms from the seminiferous tubules.
Option (4) Spermatogonia — Incorrect. Spermatogonia are the cells that start the process.

NCERT Extract:
Gametogenesis – “… The secondary spermatocytes undergo the second meiotic division to produce four equal, haploid spermatids (Figure 2.5). … The spermatids are transformed into spermatozoa (sperms) by the process called spermiogenesis. After spermiogenesis, sperm heads become embedded in the Sertoli cells, and are finally released from the seminiferous tubules by the process called spermiation.”
