Trick question. Depending on the scale, they all have the possibility of being defined as an ecosystem. But the answer they're looking for is most likely D.

The eagle nest is not part of the ecosystem because it uses the tree in the forest as a place to build a shelter. The coral reef is basicaly like a tree just it provides homes for aquadic creatures and the lake provides life for us land and aquadic animals
