Answer:
Embryonic Period
Step-by-step explanation:
Using the acronym ZEF, we can remember what order the stages of development go in:
Zygotic: Lasting only slightly less than the first two weeks (~10 days) Embryonic: When most things develop, such as the organs, spine, arms & legs
Fetal: When the stomach, facial features, hand & feet develop, with lungs being the last one, the final stage before birth and starting nine weeks in (its also when you become recognizable as human, and you become responsive to sound around the 6th month)
(I also got it right on the test lol, hope this helps)
