Solution

The correct option is B 3
Placenta also acts as an endocrine tissue and produces several hormones like human chorionic gonadotropin (hCG), human placental lactogen (hPL), oestrogens, progestogens, etc.
In the later phase of pregnancy, a hormone called relaxin is also secreted by the ovary. hCG, hPL and relaxin are produced in women only during pregnancy.
In addition, during pregnancy the levels of other hormones like oestrogens, progestogens, cortisol, prolactin, thyroxin, etc., are increased several folds in the maternal blood.
