The correct answer is - The story begins in the thick of the action.
This method is called <em>in medias res - </em>it means that the reader is immediately thrown into the action, no long introductions necessary. We are immediately told what's going on - that the Danes have a problem with the monster Grendel, and that they need Beowulf's help.
There is no lengthy introduction - we are just told that Beowulf is a great hero who can help Denmark. There is no invocation to the muse either, which is a common convention of epic poetry.
