Final Answer :
D
Explanation :
The zygote is the result of the combination of sperm and egg, and it exists during the germinal stage which spans from fertilization to the implantation of the zygote in the uterus. The embryonic stage follows the germinal stage where the zygote becomes an embryo, the fetal stage is the final stage and the conceptive stage is not a recognized stage of prenatal development.
