Answer 1

A, C, D and E only

Explanation:

The human embryo’s heart develops after one month of pregnancy. The fetus begins to grow limbs and digits toward the end of the second month of pregnancy. Most major organ systems, such as the limbs and external genital organs, are formed by the end of the first trimester, which lasts 12 weeks. The fifth month is typically when the fetus begins to move and when hair starts to grow on its head.
