A) Neonatal Stage
B) Fetal Stage
C) Embryonic Stage
D) Infancy Stage

Answer 1

The Fetal Stage (B) is the correct answer, spanning from the 9th week after conception until birth, during which significant fetal growth and organ maturation occurs.

Step-by-step explanation:

The correct answer to the student's question is B) Fetal Stage. The fetal stage is the period of prenatal development that begins at the ninth week after conception and lasts until birth, encompassing approximately 30 weeks. During this stage, the fetus undergoes significant growth, with organs becoming more mature and gradually being able to function on their own. This includes a weight increase of about seven pounds and the development of body, brain, and sensory systems.

Gestation is the term for the full development period in utero, which is around 38 weeks from fertilization for a full-term pregnancy. By the end of the fetal stage, organs are more developed, and the fetus has significantly increased in size and weight.
