B. Uterus: The uterus is where the fertilized egg implants and develops into a fetus, but it is not where fertilization occurs.
C. Ovary: The ovary is where eggs are produced and released during ovulation, but fertilization does not occur here.
D. Urinary bladder: The urinary bladder is part of the urinary system, not the reproductive system, and has no role in fertilization.
