Explanation
The correct answer is D: Both Egg and Synergids represent structures in the embryo sac of angiosperms that are analogous to the archegonium in other plants.
The archegonium is the female reproductive structure in plants that contains the egg cell and is responsible for fertilization. In angiosperms, the egg cell is located at the bottom of the embryo sac and is surrounded by two synergid cells, which help guide the pollen tube to the egg cell during fertilization. The synergids, along with the egg cell, are therefore considered to be analogous to the archegonium in other plants.
So, the correct answer is D: Both Egg and Synergids.
