Question

BlackTom AI · Accepted Answer

To start, we identify the three main periods of prenatal development and their correct chronological order: germinal, embryonic, then fetal.
Option 1: germinal, embryonic, and fetal. This sequence matches the established progression from conception through implantation (germinal), organ formation (embryonic), to growth and maturation before birth (fetal). It aligns with standard developmental timelines.
Option 2: germinal, fetal, and embryonic. Placing the fetal period before the embryonic period contradicts the actual timeline, since major development and organ formation occur during the embryonic period, not after the fetal period has begun.
Option 3: fetal, embryonic, and germinal. This reverses the true order entirely, starting with the last stage and moving backward, which misrepresents the developmental stages.
Option 4: embryonic, germinal, and fetal. Here the germinal period is placed after the embryonic period, but implantation and the initial zygote-to- embryo transition occur before embryonic development, so this order is incorrect.
In summary, option 1 faithfully mirrors the accepted sequence germinal → embryonic → fetal, while options 2, 3, and 4 disrupt the established chronology of prenatal development.
