Human chorionic gonadotropin (hCG) is produced by the placenta that helps maintain pregnancy by maintaining corpus luteum for the first trimester. Human placental lactogen is secreted by the placenta to inhibit maternal insulin activity during pregnancy. After degeneration of corpus luteum, the placenta is the source of progesterone and estrogen hormones that inhibit gonadotropins secretion and maintain pregnancy.
Therefore, the correct answer is option D.
