Answer: C. Fetal
Explanation: Prenatal development means the development of an embryo in the uterus, from the moment of fertilization of the egg, i.e. conception, until birth. This development is divided into three phases. The first phase, which is the period from the moment of conception, lasts for the next two weeks, is called germinal. The second phase is embryonic and lasts from the end of the germinal phase for the next eight weeks. The third phase, the aforementioned fetal phase, lasts from the ninth week until birth.
