Finn is intimidated by Gren in the beginning of the story and decides to change who he is to be tough like Gren at the end. C. Finn views Gren as a friend in the beginning of the story, but eventually realizes Gren won't be friends with him publically.
B is my best guess for this question
In Beowulf the character of Grendel wails in lines 781 to 789 because he has been injured. In fact his injuries are severe and he is dying.
I believe it is c. hope it helps! :)
