Estrogen
B.

ANS: C
Human placental lactogen is responsible for glucose availability for the fetus and promotes fetal growth by altering maternal protein, carbohydrate, and fat metabolism. Estrogen has multiple functions, but these do not include regulating glucose availability. Human chorionic gonadotropin maintains the corpus luteum until the placenta has developed enough to produce adequate progesterone. Among other functions, progesterone helps suppress maternal immunological responses to fetal antigens.
