Answer:
The answer is letter C. The Cyclops.
Step-by-step explanation:
In literature, an antagonist can be anything that offers some sort of conflict or hostility, maybe a challenge for the main characters. However, the antagonist is usually a character as well, one that opposes the protagonist. Thus, antagonists are often characterized as evil and dangerous, while protagonists are usually good and heroic.
In the epic poem "The Odyssey", the main character and hero is Ulysses, also called Odysseus. At a certain point in the story, he is antagonized by the Cyclops - gigantic one-eyed monsters. One of the Cyclops immediately smashes the heads of two of Odysseus' soldiers and eats them. Odysseus and his men are trapped. They only manage to escape due to Odysseus wit, courage, and intelligence.
