Read this excerpt from The Call of the Wild by Jack London.

That night Buck faced the great problem of sleeping. The tent, illumined by a candle, glowed warmly in the midst of the white plain; and when he, as a matter of course, entered it, both Perrault and Francois bombarded him with curses and cooking utensils, till he recovered from his consternation and fled ignominiously into the outer cold.

What are Perrault’s and Francois’s roles in the excerpt?

They are the protagonists because they are the main characters.
They are the protagonists because they are the leaders of the camp.
They are the antagonists because they oppose Buck’s efforts to find shelter.
They are the antagonists because they rule the dogs with cruelty and violence.
