What is the name of the female organ where a baby develops during gestation?

The correct answer is the uterus, which is the female organ specifically designed for the development of a fetus during gestation. It serves as a nurturing environment, where the fertilized egg implants itself into the uterine lining and develops into a baby over the course of approximately nine months. The uterus is structured to provide the necessary support, nutrients, and protection during this critical period of development.

In contrast, the ovary is responsible for producing eggs and hormones but does not provide a site for fetal development. The fallopian tube is the pathway through which the egg travels from the ovary to the uterus; it is also where fertilization typically occurs, but it is not the organ where a baby develops. The cervix is the lower part of the uterus, serving as a canal that connects the uterus to the vagina; while it plays a role during childbirth, it does not support fetal development either. Thus, the uterus is uniquely suited for gestation, making it the correct answer.
