The process of transformation of spermatids into spermatozoa 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 forming sperms from spermatogonia.
Option (2) Spermiogenesis — Correct. Spermatids formed by meiosis are transformed into spermatozoa (sperms) by a process called spermiogenesis. The sperm heads then get embedded in the Sertoli cells and are released from the seminiferous tubules by spermiation.
Option (3) Spermiation — Incorrect. Spermiation is the release of sperms from the seminiferous tubules, after spermiogenesis.
Option (4) Spermation — Incorrect. There is no such term.

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.”
