Natalija [7]

The correct answer is fallopian tube.

The fallopian tube, also known as uterine tube or oviduct, carries the egg from ovary to the uterus.

 The fallopian tube has finger-like projections or branches called fimbriae  which   reach out into the pelvic cavity and pick up an egg that has been released from the ovary.

The egg is tenderly brought into the fallopian tube where it begins to travel to the uterus.

The fallopian tube also serves as the location where fertilization of the egg by a sperm cell occurs.
