Correct option is B
The correct sequence of stages of
pre-natal development is:
1.
D. Conception stage: This is the stage when the sperm fertilizes the egg, marking the beginning of pregnancy.
2.
B. Germinal stage: This stage occurs in the first two weeks after conception. The fertilized egg (zygote) divides and implants itself in the uterine wall.
3.
C. Embryonic stage: From about 3 to 8 weeks, major organs and structures begin to form. This is a critical phase of development where the foundation of the body systems is laid.
4.
A. Fetal stage: This stage lasts from the 9th week until birth. During this period, the fetus grows and matures, preparing for life outside the womb.
5.
E. Delivery stage: The final stage, where the baby is born.
Information Booster:
Prenatal development is divided into three main stages:
·
Germinal stage: The first two weeks post-conception, involving fertilization, cell division, and implantation.
·
Embryonic stage: From 3 to 8 weeks, the embryo undergoes rapid development, forming the basic structures of the body.
·
Fetal stage: From 9 weeks to birth, the fetus continues to grow and develop until it is ready for delivery.
