Quizplus · Accepted Answer

The critical period is the embryonic period, which occurs from the second week to the eighth week after conception. During this time, the basic structures and systems of the body are formed, making it a crucial time for development. If a teratogen, such as alcohol or certain medications, is present during this period, it can have a profound effect that endures into adulthood. Therefore, choice C, the embryonic period, is the best choice.
