In which structure does the fertilized egg develop? ovary fallopian tube uterus vagina

The correct answer is uterus.

Explanation:

The fertilized egg, also known as a zygote, develops in the uterus after it travels from the fallopian tube where fertilization occurs. The uterus provides a suitable environment for the implantation of the zygote and its growth into a fetus. It is equipped with a rich supply of blood vessels and a thick lining (the endometrium), which supports the developing embryo. In contrast, the ovary is where the eggs are produced, the fallopian tube is the passageway for the egg to travel post-fertilization, and the vagina serves as the birth canal but is not involved in the development of the fertilized egg.

Thus, the uterus is the specific structure where the fertilized egg develops throughout the pregnancy.
