Answer:
They believe that all of their work benefits the community of animals and ultimately is for the best.
Explanation:
George Orwell's "Animal Farm" is an allegorical play showing how a group of farm animals rebelled against their human master to form their own government. The play deals with themes of greed, a struggle for power, hierarchy, corruption, equality, etc.
In Chapter V, Napoleon declared his intention to build the windmill which meant everyone must put in extra work. This meant that they will have to do their usual work added to the workload of constructing the windmill. But the animals accepted that without any complaint. Chapter VI starts with the statement<em> "All that year the animals worked like slaves. But they were happy in their work; they grudged no effort or sacrifice, well aware that everything that they did was for the benefit of themselves and those of their kind who would come after them, and not for a pack of idle, thieving human beings."</em>
This shows that the animals readily accepted the increased workload because they believed that it is for the benefit of the whole community and their future generations.
Thus, the correct answer is the second option.
