  1. A.hCG, hPL, progestogens, estrogens✓
  2. B.hCG, hPL, estrogens, relaxin, oxytocin
  3. C.hCG, hPL, progestogens, prolactin
  4. D.hCG, progestogens, estrogens, glucocorticoids

Correct Answer

(A) hCG, hPL, progestogens, estrogens

Solution & Explanation

Answer: (A) hCG, hPL, progestogens, estrogens Solution: NCERT states the placenta acts as an endocrine tissue and produces several hormones including human chorionic gonadotropin (hCG), human placental lactogen (hPL), estrogens and progestogens, which support fetal growth and maintenance of pregnancy. Relaxin (option B) is secreted by the ovary, not the placenta, and oxytocin/prolactin are not placental products, eliminating the other options. NCERT Reference: Ch 2, p.37, line 24 — "several hormones like human chorionic gonadotropin (hCG), human"
