Final Answer :
B
Explanation :
The longest stage of prenatal development is the fetal stage, which lasts from the 9th week after fertilization until birth. The embryonic stage lasts from the 3rd to the 8th week after fertilization. The zygotic stage refers to the very early period of development immediately after fertilization, and the germinal stage refers to the period from fertilization to the implantation of the zygote in the uterine wall. Neither of these stages is as long as the fetal stage.
