Solution
The correct option is A Secretes oxytocin during parturition
The placenta is a cushion-like tissue which facilitates the supply of oxygen and nutrients to an embryo and also the removal of carbon dioxide and excretory waste materials produced by the embryo. It also acts as an endocrine tissue and produces several hormones such as human chorionic gonadotropin, human placental lactogen, estrogens, progesterone and relaxin.
So, the correct option is 'Secretes oxytocin during parturition'.
