Answer:
Fetus
Explanation:
A zygote, embryo, and blastocyst, are within the first few weeks for pregnancy. By weeks 7-9 the baby starts to grow arms, legs, ears, eyes, and more. And by 9 weeks, the baby's hair follicles grow, and so do the arms and legs as they grown longer. So by about week 10, you might be able to see and predict the baby's eye colour, and so forth.
Which leads up to the point that the baby is a fetus.
Hope this helps! :)
