Answer:
The best answer to the question: Which lines best illustrate the conclusion that Odysseus is an epic hero because he fights alone, would be: Lines 23-24.
Explanation:
This part of the narration of the Odyssey, which takes place in Book 12, when Odysseus and his crew finally leave Circe to continue on their journey to Ithaca. As warned by Circe herself, Odysseus takes measures as he knows that they will be passing the island of the Sirens, and that if not careful, they can all perish under siren song. So, he stuffs his crew´s ears with beeswax and then orders his men to tie him up to the mast of the ship and not let go no matter what happens. Odysseus alone decides to face the fight of supernatural beings, the Sirens, while he ensures that his men are all taken care of and are safe. In lines 23 to 24, is where Odysseus himself lets us know of his decision to face the terrible situation and the orders that he gives his men. We see him facing these supernatural beings and protecting his men from them.
