How does the animal rebellion initially begin?

The rebellion on the farm starts as a direct response to the neglect and mistreatment that the animals endure at the hands of their human owner, Mr. Jones. This oppressive environment creates a strong sense of discontent and injustice among the animals. They are overworked, underfed, and generally treated with disregard, which fosters a collective desire for change and improvement in their living conditions. Inspired by the ideals of Animalism and the belief that they could govern themselves better than humans, the animals unite and rise against Mr. Jones, ultimately leading to the overthrow of human rule.

The other options do not accurately capture the driving force behind the rebellion. Forming alliances with other farms or being influenced by human leaders would imply a more strategic or external motivation, while a misunderstanding does not reflect the clear and rational grievances the animals share regarding their treatment.
