Solution

The correct option is A It cannot produce hormones
The placenta is an organ that develops in the uterus after implantation of the embryo. It facilitates the supply of oxygen and nutrients to the growing embryo. It also facilitates removal of CO2 and excretory waste materials from the embryo. Placenta also acts as an endocrine tissue and produces
several hormones like human chorionic gonadotropin (hCG), human placental lactogen (hPL), estrogens, progesterones, etc.
