The _________ is a temporary organ that connects a mammalian mother to its foetus.
Correct Answer: A
Rationale: The correct answer is A: Placenta. The placenta is a temporary organ that connects a mammalian mother to its foetus by facilitating the exchange of nutrients, gases, and waste products between the mother and the developing baby. It also produces hormones necessary for pregnancy.
Explanation of other choices:
B: Chorion - The chorion is a membrane that surrounds the embryo and contributes to the formation of the placenta, but it is not the organ that directly connects the mother to the foetus.
C: Endometrium - The endometrium is the inner lining of the uterus where implantation of the fertilized egg occurs, but it is not the organ that connects the mother to the foetus.
D: None of the above - This choice is incorrect as the placenta is indeed the temporary organ that serves as the connection between the mother and the foetus in mammalian reproduction.
