The correct answer is B. Gilgamesh.
Odyssey and Iliad deal with the Troyan war and it's aftermath while Beowulf deals with heroic endeavors of the main character, Beowulf. The epic of Gilgamesh is one of the oldest epics ever and is from the Mesopotamian culture.

Many official buildings built in the US are very strongly influenced by Greek and Roman architecture. The most obvious being the White House, which displays Roman and Greek influences in the arches and columns on the exterior, and in the windows seen on the White House. While initially developed by the Greeks, arches and other architectural designs were incorporated by the Romans and can still be seen within ancient Roman architecture. Many Greek designs still resonate and "echo" into modern western architecture to this day.
Hope this helps :)
