Best answer

Answer: 2. hCG, hPL, progestogens, estrogens

Key idea: The placenta works as a temporary endocrine gland.

It secretes hCG, hPL (human placental lactogen), estrogens and progestogens to maintain pregnancy. Relaxin is secreted in later pregnancy, and prolactin, oxytocin and glucocorticoids are not placental hormones needed for this purpose. Only option 2 lists the four correctly.

Answer: option 2.
