The correct answer is A.
This passage realtes the events that reveal to the reader that Anderson is being discriminated due to his race.
When Anderson wants to book the hall, he is told that there are no dates available. Suspicious, he asks a white pianist to do the same, and the man is given a date in no time. This makes Anderson understand that the reason why he was not allowed to book the place was the colour of his skin.
Answers B, C and D are incorrect because the paragraph does not use figurative language, is not foreshadowing any events, and does not present a dialogue.
