Answer:
A) temper; plot
Explanation:
The first half focuses about neutralizing or moderating thoughts and rhetoric of revolutionaries which corresponds to the definition of the term "temper". This runs in contrast with the concept of going against the government requiring planning, plotting or forming hidden schemes. This is connected to the term "plot".
The best option seems to be the second one, letter B) This concept is mentioned throughout the book.
The book The Call of the Wild, by Jack London, has as its theme the concept of "survival of the fittest". Survival of the fittest is an expression connected to Charles Darwin's theory of evolution. Organisms which are able to adapt to the environment survive. Those which are not end up extinct.
That is precisely what happens in the story by London. The main character is a dog, Buck. Buck is stolen from a family with whom he lived a comfortable life. He has to adapt to a whole new environment and conditions as a sled-dog. He turns out to be so adaptable that he becomes the leader of a pack of wolves by the end of the story.
