Explanation:

The age of viability is the point at which a fetus has a chance of surviving outside the womb. The prenatal age refers to the time from conception until birth. The term "age of sustainability" is not a standard term in this context. Gestational age is the age of the embryo or fetus calculated from the first day of the woman's last menstrual period. So, the correct answer is B as it specifically refers to the age when a fetus can survive outside the mother's body.

Answer:

B. age of viability
