Step-by-step explanation:
The animals were still very happy despite 'working like slaves' primarily B) Because they believed in the principles of equality and freedom. The animals in George Orwell's 'Animal Farm' are a metaphor for the struggles of the working class. Like many laborers throughout history, their conditions were arduous, yet they found solace in their beliefs.
Whether it was the belief in a better future or the satisfaction derived from working towards a collective goal, these ideologies often provided the necessary motivation for laborers to continue despite the lack of comfort, the extended working hours, or the minimal sustenance provided.
The narrative in 'Animal Farm' follows the animals' pursuit of a society where all creatures are equal. This ideal resonated not just on a fictional farm but echoes the sentiments of serfs, slaves, and workers throughout different historical periods. The sense of purpose and the belief in a collective ideal gave strength to many oppressed individuals, allowing them to endure the hardships of laborious work with a semblance of happiness.
