(c) spermatogonia, spermatocyte, spermatid, spermatozoa
(d) spermatid, spermatocyte, spermatogonia, spermatozoa

Correct Answer:

spermatogonia, spermatocyte, spermatid, spermatozoa

Explanation:

In testis, the immature male germ cells or spermatogonia (2n) multiply by mitotic divide and increase in number. 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.
