Prenatal development

Explanation:

Prenatal development is the phase of growth and development in which a single-celled zygote grows into an embryo followed by the fetus and then a baby in the womb of a lady.

The process of prenatal development is very complicated which is divided into three phases:

1. Germinal phase: during the first two weeks after the conception in which the single-celled zygote develops.

2. Embryonic period: during which the zygote grows into the embryo and lasts from the second week to the eighth week.

3. Fetal period: During which the embryo grows to form a fetus which matures into a baby and is born.

Thus, Prenatal development is the correct answer.
