Answer:
The correct answer is option B. "four haploid cells".
Step-by-step explanation:
Sperm, also known as spermatozoa, is produced by a special type of cellular reproduction called spermatogenesis. Spermatogenesis is a subtype of meiosis, at which a diploid parent cells divided its genetic material in half, and produces four haploid cells. Spermatogenesis starts with a mitotic division of spermatogonial stem cells, then type B cells differentiate into spermatocytes. Later, spermatocytes divide into two secondary spermatocytes and finally, four haploid spermatids are produced in the last stage.
