Fertilization site in human reproduction

Steps:

• Stage 1: Ovum released from ovary via ovulation.
• Stage 2: Ovum travels through oviduct, meeting sperm for fertilization.
• Zygote forms and moves to uterus for implantation.
• Development continues to fetus in uterus.

Why B is correct:

• Fertilization, the fusion of sperm and ovum, occurs in the oviduct per human reproductive anatomy.

Why the others are wrong:

• A: Ovary releases ovum but does not host fertilization.
• C: Uterus supports implantation and pregnancy, post-fertilization.
• D: Vagina is entry for sperm but not fertilization site.

Final answer: B
