Which of the following stages of the fertilization process stimulates completion of meiosis II in the oocyte’s nucleus? A. The sperm nucleus and egg nucleus combine to form the genetic material of the zygote B. Sperm release enzymes to digest the protein layer of the secondary oocyte C. The entry of a sperm into the secondary oocyte D. The swimming of sperm from the vagina, through the uterus, and up to an oviduct
