Q.
Find the odd one out with respect to hormones secreted by placenta.

Solution:
$\text{hCG, hPL,}$ estrogens and progestogen hormones are produced by the placenta in women only during pregnancy. Oxytocin is released by the maternal pituitary gland (neurohypophysis) at the time of childbirth due to fetal ejection reflex. Relaxin is produced by ovary only during pregnancy.
