How does the notion of 'us versus them' manifest in Animal Farm?

The notion of 'us versus them' in Animal Farm is primarily represented through the division between the pigs and the other animals on the farm. The pigs, who position themselves as the ruling class, use this mindset to justify their privileges and authority. They create an elite group by emphasizing their supposed superiority in intelligence and governance. This division is most clearly illustrated in the way the pigs gradually alter the commandments of Animalism to benefit themselves, leading to an increased disparity between the pigs and the other animals. By framing the other animals as workers who are inferior and dependent on the leadership of the pigs, this division reinforces their control and allows them to exploit the labor of the other animals while maintaining power. The other options do not accurately represent this fundamental theme, as they suggest unity or cooperation rather than highlighting the clear segregation and manipulation present among the animals on the farm.
