Final Answer :
D
Explanation :
The fetal period begins at the 9th week of gestation and lasts until birth. During this period, the organs continue to develop and mature, and the fetus grows in size and weight. This is the longest period of gestation and is marked by rapid changes in the fetus's development. Choice A (zygotic period) refers to the first two weeks after fertilization, while choice B (embryonic period) refers to the period from the 3rd to the 8th week after fertilization. Choice C (germinal period) refers to the first 2 weeks after fertilization, during which the zygote undergoes cell division and begins to implant in the uterine lining.
