Best answer
The correct choice is (b) Umbilical cord

The explanation is: Placenta provides nutrition and a medium for the removal of wastes for the fetus. This occurs via the umbilical cord, which connects the fetus to the placenta. The cord remains attached even after the birth and needs to be removed surgically.
