- D.Statement I is incorrect but Statement II is correct
Correct Answer
(B) Both Statement I and Statement II are incorrect
Solution & Explanation
Answer: (B) Both Statement I and Statement II are incorrect Solution: Statement I is wrong because spermiation is the release of sperms FROM (not into) the seminiferous tubules — sperm heads first become embedded in Sertoli cells and are then released from the tubules. Statement II is wrong because spermiogenesis is the transformation of spermatids into spermatozoa, not the formation of sperms from spermatogonia. Hence both statements are incorrect.
