Solution
The correct option is D Nerves
The placenta is an organ, that connects the fetus to the uterine wall. This allows the nutrient uptake, waste elimination and gas exchange via the mother's blood supply, fights against internal infection and produces hormones to support pregnancy. Placenta connects the fetus by an umbilical cord which contains two umbilical arteries and one umbilical vein. The placenta is encircled by a ring of smooth muscle cells.
The placenta does not have nerves.
Thus, the correct answer is option (D), 'Nerves'.
