The correct answer is C. Because it is one of the few words a raven can say. The speaker, a man who grieves for his deceased love, Lenore, has been visited by a talking bird who only know one word: Nevermore. He was so depressed of having lost his love that he allows his imagination to transform the bird into a prophet bringing news that the lovers will "Nevermore" be together.
Answer and Explanation:
Sofocles decided that the catastrophe involving Oedipus and Jocasta should take place offstage and that these facts be presented by a servant. This decision was made to allow the narrative to increase dramatically, without being appealing and stimulating the public's imagination.
This is because when the servant is placed as the bearer of the catastrophe information, the public can use his words and create his own image of what happened and may even doubt that the facts narrated are real. Sofocle, then, gave the public autonomy over the tragic end of the story.
