Quizplus · Accepted Answer

The stages of prenatal development are typically divided into three periods: preimplantation (which covers the first two weeks after conception, during which the zygote travels down the fallopian tube and implants in the uterus), embryonic (which covers weeks 3-8, during which the major organ systems are formed), and fetal (which covers weeks 9-40, during which the organs and systems continue to mature and the fetus grows in size). While A and B refer to different developmental processes (formation of the three germ layers and growth of specific structures, respectively), they do not encompass the entire prenatal period. D refers to specific moments within prenatal development, but not to the broader stages in which they occur.
