The correct answer is C. The story's conflict will be based on wealth and appearances
Step-by-step explanation:
The excerpt focuses on describing the setting, especially the contrast between the East Egg and the West Egg. This can be seen in details such as "My own house was an eyesore" that shows the narrator is likely at the West Egg which has non-luxurious houses, or in "the white palaces of fashionable East Egg glittered along the water" that shows the extravagance of the East Egg.
This important contrast between the East Egg and the West Egg suggests the story will likely focus on the conflict between these two places especially a conflict related to wealth or appearances in the East Egg as the narrator mentions "and the history of the summer really begins on the evening I drove over there", which confirms the focus is the East Egg and its features.
