Solution

The correct option is B 2 umbilical arteries and 1 umbilical vein
The umbilical cord is the structure that forms the connection between placenta and the foetus. It keeps the foetus connected to the placenta for facilitating the diffusion of substances across the placenta. There are two umbilical arteries and 1 umbilical vein. The umbilical arteries carry the deoxygenated blood from the foetus to the placenta and the umbilical veins carry the oxygenated blood to the foetus from the placenta.
