Placentation -

  • After implantation, finger-like projections appear on the trophoblast called the chorionic villi which are surrounded by the uterine tissue and maternal blood. 
  • The chorionic villi and uterine tissue become interdigitated with each other and jointly form a structural and functional unit between developing embryo (foetus) and maternal body called the placenta.
  • The placenta facilitates the supply of oxygen and nutrients to the embryo and also removal of carbon dioxide and excretory/waste materials produced by the embryo. 
  • The placenta is connected to the embryo through an umbilical cord which helps in the transport of substances to and from the embryo. 

Hence, the correct option is (d).
