Final answer:
Beowulf's actions of being willing to fight the dragon in his old age indicate his courage and determination to protect his people (option a). The author of Beowulf has depicted Beowulf as honorable by showing his bravery and willingness to fight against the dragon.
Step-by-step explanation:
The actions of Beowulf in being willing to fight a dragon even in his old age can be inferred as him still being courageous and determined to protect his people. This shows that Beowulf has not retired from heroics and is still committed to defending his kingdom.
One piece of evidence from the text that supports this conclusion is in line 697-735 when Wiglaf gives details that depict Beowulf as an honorable king. The author of Beowulf has depicted Beowulf as honorable by showing his bravery and willingness to fight against the dragon, even though it may result in his own death. This demonstrates Beowulf's dedication to his people and his commitment to fulfill his duty as a leader.
