Answer:
B
Step-by-step explanation:
As the passage states, they danced as well as any of their courtiers and were dressed in rich clothes and masks people said they believed they were human dancers, but then a mischievous courtier took a handful of nuts then threw it on stage, then the monkeys started fighting and forgot their dancing, and they ripped off their rich clothes, so what happened during the end was that the audience thought they were just normal dancers, but when they started fighting and ripping their clothes off, the people realized they weren't like they thought they would be.
