Vedclass · Answer

(A) During pregnancy,the placenta acts as an endocrine tissue and produces several hormones essential for fetal development and maintenance of pregnancy. These include $hCG$ (human Chorionic Gonadotropin),$hPL$ (human Placental Lactogen),Estrogen,and Progesterone. Relaxin is also secreted by the ovary during the later stages of pregnancy. However,among the given options,$hCG$ is a hormone produced exclusively by the placenta during pregnancy,whereas Estrogen,Progesterone,and Relaxin can be produced by the ovaries in a non-pregnant state as well. Therefore,$hCG$ is the odd one out.
