At the end of month 3, the embryo is officially called a fetus. Which option correctly identifies this milestone?

Explanation:
Understanding prenatal development stages helps explain this milestone. An embryo is the developing baby in the early weeks, and as growth progresses—major organ systems form and the body takes on a more recognizable human shape—the term shifts to fetus. In common educational charts, this transition is marked by the end of the first trimester, which is about the end of the third month. So by the end of month three, the developing baby is typically labeled a fetus rather than an embryo. The other time points describe earlier or later stages and don’t match when the embryo-to-fetus change is defined in most study materials.
