Question

Quizplus · Accepted Answer

By the eighth week following conception, the embryonic stage ends and the fetal stage begins. Therefore, the best choice is B, fetus. The prenatal period refers to the entire period of development from conception to birth, so choice A is too broad. The zygote stage occurs immediately after fertilization, while the embryo stage occurs from approximately the third week to the end of the seventh week, so choices C and D are too early in the development process.
