Answer:
A). The long list of names required to address certain nobles.
Step-by-step explanation:
In the given excerpt, Twain satirizes 'the long list of names required to address certain nobles' which is clearly reflected through the description of the people's different ranks and positions attached to their names(like Lady Anne-Grace-Eleanor-Celeste- and-so-forth-and-so-forth-de-Bohu, Countess of Newgate, etc.'). The key purpose of focusing on the names instead of the description of the ball reflects that the author aims to critique the follies/vices of the British people who laid such emphasis on the names and the positions associated at the time. Thus, option A is the correct answer.
