Varun Aggarwal · Accepted Answer

Final Answer : A, Explanation :  The amnion is the innermost membrane of an embryo and develops early in embryonic development. It protects the embryo by enclosing it in a fluid-filled sac. The placenta is an organ that connects the developing fetus to the uterine wall to allow nutrient uptake, waste elimination, and gas exchange via the mother's blood supply. The blastula is an early stage of embryonic development characterized by a hollow ball of cells. The acrosome is a specialized structure in the head of a sperm cell that contains enzymes to help penetrate the egg. None of these structures refer to the inner membrane of an embryo, except for the amnion.
