Quizplus · Accepted Answer

Viability refers to the point in gestation when a fetus has the potential to survive outside the uterus with medical intervention. This typically occurs between 22 and 28 weeks of gestation, although outcomes can vary depending on various factors. Therefore, choice (A) is the correct answer. Option (B) is incorrect because teratogens have the potential to affect fetal development at any stage of pregnancy. Option (C) is incorrect because twinning typically occurs earlier in gestation, around the time of implantation (around 10-14 days after fertilization). Option (D) is incorrect because, while some infants born before the age of viability may survive without medical intervention, it is relatively rare and not a guarantee.
