Why is it important to Grendel that his death be viewed as an accident?

A. Since he wants Unferth to be the hero, he doesn't want Beowulf to
receive the credit

B. Since he does not want his mother to seek revenge, he needs her
to think it was an accident.

C. Since he hides the truth about his special power, he doesn't want
anyone to discover the truth.

D. Since he believes life is meaningless, he needs his death to have
no purpose
