Question

Quizplus · Accepted Answer

The formation of the o-tube occurs within the first 21 days of pregnancy. By this time, the fertilized egg would have traveled through the fallopian tube and implanted in the uterine wall. The o-tube then forms the basis for the development of the embryo and ultimately the fetus. Option A is too soon for the formation of the o-tube, while options B and D are too late in the pregnancy timeline for this process.
