Answer:
D)Both A and B
Step-by-step explanation:
King Beowulf wants glory for himself and comes to the aid of a troubled nation that is tormented by the beast Grendel.
His decision to fight Grendel without weapons is because he is an honorable man who refuses to fight the monster who does not fight with a sword, with one.
Another reason was that his king Higlac would be disappointed in him if he did otherwise because he knows what a great warrior Beowulf is.
