Hormones secreted by the placenta to maintain pregnancy are:

Correct option is B

Correct Answer: (b)
Explanation:
The placenta secretes hCG (Human Chorionic Gonadotropin), hPL (Human Placental Lactogen), estrogens, and progestogens to maintain pregnancy and support fetal development.
Information Booster:
hCG maintains the corpus luteum and progesterone production.
hPL (Human Placental Lactogen) modifies maternal metabolism to supply nutrients to the fetus.
Progesterone maintains uterine lining and prevents contractions.
Estrogen promotes uterine growth and breast development.
Oxytocin is not placental; it is secreted by the posterior pituitary to induce labor.
Additional Information:
(a) Incorrect – oxytocin is not produced by placenta.
(c) Glucocorticoids are adrenal hormones, not placental.
(d) Prolactin is secreted by the anterior pituitary, not the placenta.
