Process of fertilization

• A. Egg is released from ovary and travels down the fallopian tubes
• B. Egg joins with sperm
• C. If collision happens, the fertilized egg rests on the lining of the uterus
• D. The placenta forms

Answer: (C)

After fertilization occurs, the fertilized egg (zygote) travels to the uterus and embeds itself into the uterine lining. This implantation is essential for pregnancy to continue, and the placenta forms later to support the growing embryo. The other statements describe earlier steps or later developments (ovulation and transport to the fallopian tube, the actual join of egg and sperm, and placenta formation), so the statement about the fertilized egg resting on the uterine lining best captures what happens following fertilization.
