Explanation:

• Eutherians (placental mammals) have a full placenta that allows for extensive nutrient and gas exchange between mother and fetus, enabling the development of well - developed young.
• Marsupials have a simple placenta. Their young are born at a very early stage of development and then complete their development in a pouch.
• Monotremes are egg - laying mammals and have no placenta. They lay eggs and the young hatch from the eggs and are then nourished by milk.

Answer:

• Eutherians: full placenta
• Marsupials: simple placenta
• Monotremes: no placenta
