Zielflug [23.3K]

Answer:

The correct answer is D. zygote and finally develops into a fetus

Explanation:

Zygote is formed by the fusion of male gametes and female gametes. It is considered as the first stage of development of a baby. Zygote is a unicellular structure which develops into an embryo which is a multicellular structure.

Then this embryo develops and is called a fetus at the starting of the 11th week of pregnancy. A developed fetus is the final stage of prenatal development.

Therefore during successful prenatal development, a human baby begins as a zygote and finally develops into a fetus. So the correct answer is D.
