A Correct answer
Explanation

In mammals, fertilization (the fusion of sperm and egg) occurs in the fallopian tubes (also called oviducts), not in the ovary or uterus. The ovulated egg is swept into the fallopian tube where it may encounter sperm. After fertilization, the zygote travels to the uterus for implantation. This is why ectopic pregnancies can occur in the fallopian tubes if the fertilized egg fails to reach the uterus.
