Answer:
D. mystery and interest.
Step-by-step explanation:
F. Scott Fitzgerald's "The Great Gatsby" tells the story of a lost American dream and the attempts to get back what was in the past. It also revolves around the theme of loyalty, the sense of belonging and the need to be accepted by the others.
The given passage is from the very first chapter of the text where the narrator Nick Carraway mentions and encounters our protagonist Jay Gatsby for the very first time. He had gone to Daisy and Tom Buchanan's house in East Egg for dinner after which he returned to his place in West Egg. He knows about his neighbor Gatsby but hasn't really met him. So, when he realized that he wasn't alone outside, and saw Gatsby in his own balcony too, he was intrigued yet also finds it mysterious. This literal image of Gatsby emerging from the darkness to the light creates a sense of mystery yet interest in the narrator about his neighbor.
