<h3>What is conflict?</h3>

When it comes to literature, we call conflict any friction or encounter between two opposing forces. There are several different types of conflict, but a common one is character versus character, which is precisely the one in this excerpt.

In the excerpt from "Animal Farm," we see a conflict between characters Napoleon and Snowball. Both are responsible for governing the farm, but they want different things. While Snowball wants to encourage the animals to revolt in other places, Napoleon wants them to protect themselves.

With the information above in mind, we can choose option D as the correct answer.

The missing excerpt for this question is the following:

Apart from the disputes over the windmill, there was the question of the defense of the farm. It was fully realized that though the human beings had been defeated in the Battle of the Cowshed they might make another and more determined attempt to recapture the farm and reinstate Mr. Jones. They had all the more reason for doing so because the news of their defeat had spread across the countryside and made the animals on the neighbouring farms more restive than ever. As usual, Snowball and Napoleon were in disagreement. According to Napoleon, what the animals must do was to procure firearms and train themselves in the use of them. According to Snowball, they must send out more and more pigeons and stir up rebellion among the animals on the other farms. The one argued that if they could not defend themselves they were bound to be conquered, the other argued that if rebellions happened everywhere they would have no need to defend themselves. - Animal Farm, George Orwell.
