Final answer:
During the Fetal Period of Prenatal Development, the organs have previously been formed and the fetus will make gains in height and weight.
Step-by-step explanation:
The correct answer is D. BOTH A & C.
During the fetal period of prenatal development, which begins about 2 months after conception, the organs have previously been formed (option A). By this time, the major body organs are recognizable as a human being, although they are not yet fully developed and functional. Additionally, during the fetal period, the fetus will continue to make gains in height and weight (option C). The fetus rapidly puts on body fat and gains weight during the last couple of months of development.
