Plz help sir

Dear student,
Please find below the answer:

8. The correct option is (B). The cells labelled as A, B and C are spermatogonia, Sertoli cells and primary spermatocytes. 

9. The correct option is (B). The process of spermatogenesis requires a lower temperature to produce viable sperm, specifically 1°-8 °C lower than the normal body temperature of 37 °C (98.6 °F). 

10. The correct option is (D). The process of spermatogenesis begins at puberty. At this point, the hypothalamus begins to secrete gonadotropin-releasing hormone (GnRH). GnRH stimulates the anterior pituitary to secrete the gonadotropic hormones follicle-stimulating hormone (FSH) and luteinizing hormone (LH). While LH stimulates the interstitial cells to secrete testosterone, FSH stimulates Sertoli cells to secrete androgen-binding protein (ABP) and other signalling molecules, that are necessary for spermatogenesis. 

Hope this clears your doubt.
Regards.
