Answer

Brief Explanations:

The placenta is an organ that facilitates the exchange of oxygen and nutrients from the mother to the embryo and removes waste products from the embryo. The blood of the mother and fetus do not mix directly. It cannot screen out all harmful substances, and it has no role in providing breast - milk taste.

Answer:

The first option: provides the embryo with oxygen and removes waste products.
