The correct answer is secondary spermatocytes.In the seminiferous epithelium of the testes, the cells that undergo the second meiotic division are the secondary spermatocytes. The process of spermatogenesis involves several stages of cell division and differentiation:1. Spermatogonia: These are the diploid stem cells located at the outer edge of the seminiferous tubules. They undergo mitotic division to produce primary spermatocytes.2. Primary spermatocytes: These are the diploid cells that undergo the first meiotic division to produce two haploid secondary spermatocytes.3. Secondary spermatocytes: These are the haploid cells that undergo the second meiotic division to produce four haploid spermatids.4. Spermatids: These are the haploid cells that undergo a series of differentiation steps to become mature spermatozoa.5. Spermatozoa: These are the mature, motile sperm cells that are released into the lumen of the seminiferous tubules.Therefore, the cells that undergo the second meiotic division in the seminiferous epithelium are the secondary spermatocytes.
