• A. Endometrium
• B. Uterus
• C. Placenta
• D. None of the above

Answer 1

Answer: (C)

Placenta

The placenta is a temporary organ formed in the eutherian (placenta) mammals only. The placenta is formed of the tissues between the foetus and the mother. In the placenta, the foetal blood comes very close to the maternal blood, and this permits the exchange of materials between them. Food, water, minerals, vitamins hormones, antibodies, oxygen pass from the maternal blood into foetal blood and foetal metabolic wastes such as carbon dioxide, urea etc, pass into the maternal blood.

So, the correct answer is option C.
