Prenatal development can be thought of in terms of the germinal, embryonic, and fetal periods. Or, it can be thought of as three trimesters. In terms of the way time is divided into periods, these two viewpoints are

A) identical; they both see prenatal development as occurring in three 3-month periods.
B) identical; they both see prenatal development as divided into the first two weeks, week 3 through 8, and the third month through birth.
C) similar in that both assume a pregnancy will last 266 days.
D) different in how development is viewed.
