46
B
23
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Each human somatic cell is diploid with a set of pair of 23 chromosomes, so the total number of chromosomes is 46. Spermatogonia are also diploid in nature having 46 chromosomes.

Detailed explanation-2: -It has 23 chromosomes. Hence, the correct option is C-Secondary oocyte. Note: The spermatogenesis and oogenesis are the processes of the formation of male gametes and female gametes.

Detailed explanation-3: -Spermatogonia are diploid cells that have 46 chromosomes. Therefore the spermatids will have 23 chromosomes.

Detailed explanation-4: -Spermatogonia, the primordial male germ cells that are the precursors of spermatozoa multiply by mitosis throughout adult life. Spermatogonia initiate myosis by duplicating their DNA to yield 46 chromosomes each with 2 daughter chromatids. At this stage the germ cells are called primary spermatocytes.
