Which statement from the passage most clearly establishes characterization for Unferth?
Answer:
C. [T]he journey of Beowulf, / the brave seafarer, caused him chagrin.
Characterization is a description of character, traits, etc.
Chagrin is a feeling of annoyance.
So this line describes some traits of Unferth's character. He is jealous of Beowulf; that's why Unferth is annoyed to hear about Beowulf's heroic deeds. In a way, he feels inferior to Beowulf.
