Quizplus · Accepted Answer

The pre-embryonic period begins with fertilization, which occurs in the oviduct (also known as the fallopian tube). Therefore, the correct choice is C, in the oviduct. The uterus is where the embryo implants and develops. The ovary is where the oocyte (egg) is released during ovulation.
