Answer:
Frederick’s violence is exaggerated to promote distrust of humans and faith in their leader is the correct answer.
Step-by-step explanation:
Animal Farm is a novel written by English author George Orwell; it narrates the story of a group of animals that takes control over a farm led by the pigs. The excerpt belongs to the part before the rebellion and the effects of propaganda can be seen when the narrator mentions that "the animals blood boiled in rage" after listening the stories about Frederick and his violence towards other animals and how this helped Comrade Napoleon, so the last option is correct.
