Which character is described in these lines?

"Forward the foeman foined with his hand;

Caught he quickly the cunning deviser"

The quote is from Beowulf (Ch12: Grendel and Beowulf)

Here are the choices:

a. Beowulf

b. Grendel

C. Hrothgar

D. Higelac

The character who is described in these lines is B. Grendel. You can see in the excerpt that it says that the monster killed many people in his lifetime, but that now he has found someone who is equal in strength, or rather even stronger. Beowulf managed to kill the monster Grendel, and their fight can be seen in these lines.

The answer isn't B. Grendel, I just got it wrong.
