Which best summarizes the event from the poem contained in these lines? "thee i would therefore beg of the bounty, bright-danish chieftain, lord of the scyldings, this single petition: not to refuse me, defender of warriors, friend-lord of folks, so far have i sought thee, that i may unaided, my earlmen assisting me, this brace-mooded war-band, purify heorot

If the options are:

a. King Hrothgar asks Beowulf to fight with his men against Grendel. 
b. Grendel kills several of King Hrothgar's men and steals his treasure. 
c. Beowulf says he will defeat Grendel in exchange for great fortune. 
d. Beowulf asks King Hrothgar to allow him and his men to destroy Grendel.

Then the correct answer is d. This is Beowulf speaking, and "Bright-Danish chieftain, Lord of the Scyldings" is King Hrothgar. Beowulf refers to himself as "defender of warriors, friend-lord of folks", and says that he has come from afar with his warriors to purify - to purge the Heorot Hall from malice brought by Grendel. Beowulf doesn't ask Hrothgar for help; he will destroy Grendel with the help of his own friends.

It's a gift from god that allows people to bear witness to horror.
