The correct answer is Uterus.

The uterus, also known as the womb, is a significant organ in the female reproductive system where a fertilized egg implants and develops during pregnancy. It is a muscular structure that provides a protective environment for the developing fetus, supporting its growth and nourishment until birth.

During the early stages of pregnancy, the uterine lining thickens to support the embryo. As the fetus develops, the uterus expands to accommodate its growth. The cervix, while being an essential part of the reproductive system, serves primarily as the passage between the uterus and the vagina and plays a crucial role during childbirth but does not act as the location for fetal development.

Therefore, among the given options, the uterus is the organ that the fetus will stay in until birth.
