(d) spermatid, spermatocyte, spermatogonia, spermatozoa
Correct Answer:
spermatogonia, spermatocyte, spermatid, spermatozoa

Some spermatogonia (2n) known as primary spermatocytes divide meiotic division to form secondary spermatocytes (n). The secondary spermatocytes undergo second meiotic division to produce spermatid which are transformed into spermatozoa (sperms) by the process called spermiogenesis.
