Answer:D) The secondary spermatocyte is diploid; the spermatids(haploid)
Explanation:
The process of production of both diploid chromosomes(2n) of spermatocytes and haploid chromosomes(n) spermatids is called Spermatogenesis.
It is a process of gametes production in males which begins in the semineferous tubules of the testis with spermatogonia stem cells and conpleted in the epididymis.
It begins at puberty.
The spermatogonia (2n)divided by mitosis to type A and type B cells.The type B cells formed the 2 primary spermatocytes. Type B are Nutritive in function.
These cells divided by meiosis at meiosis 1 (reduction division) into 2 secondary spermatocytes..
The latter cells divided to 2 haploid spermatids cell( each with haploid chromlsomes( n) that is,half of what is found in the spermatogonia)by second Meiotic division(n)/meiosis 2.
The spermatids formed the spermatozoa by the process of spermiogenesis.

I n summary the primary spermatocytes gives (2 ) secondary spermatocytes while each of these divided into 4 spermatids.That is 2 each from spermatozoa.
