Final answer:
The prenatal stage describes the period between conception and birth, encompassing the germinal stage, the embryonic stage, and the fetal stage, with the prenatal stage being the correct answer to the student's question.
Step-by-step explanation:
The developmental stage between conception and birth is called the prenatal stage. There are three stages within the prenatal period: the germinal stage, embryonic stage, and the fetal stage. During the germinal stage, which lasts about two weeks from conception, the zygote undergoes cell division and eventually implants into the uterus. Following this, the embryonic stage, from approximately weeks 3 to 8 after fertilization, signifies a period where the basic forms of the organ systems develop. After this, the fetal stage begins at the start of the ninth week and continues until birth, marked by the growth and maturation of the already formed organs and systems.
