Answer:
B. Odysseus is the only one in his crew referred to by name.
Step-by-step explanation:
A. this is not the correct answer. There is nothing about giving the speech that would make Odysseys the protagonist.
B. this is the correct answer. By referring Odysseus by the name and leaving other crewmembers nameless, Homer singled him out as the center of the story. He is the only one worth naming and the only one on which we should focus our attention.
C. this is not the right answer. Him being confident and boastful are not traits that only specifically protagonists have.
D. is not the right answer. While Odysseus is descended from kings (Laertes and Arcesius) this is not the trait specifically meant for protagonists only.
