Answer: c. Jay Gatsby
Explanation:
Jay Gatsby is the main character of Fitzgerald's novel, <em>The Great Gatsby</em>.
In the novel, Nick Carraway tells a story about his seemingly mysterious neighbor, Jay Gatsby. Gatsby first appears in Chapter 3, but up to this point, we already become familiar with the rumors that spread about Gatsby's rise to wealth.
Gatsby's first appearance is probably different from what the reader might expect - he is described as just another man around thirties who attends the party, until it is revealed that he is, in fact, Jay Gatsby. It turns out that Nick and him served in the same division during the war. Gatsby's first appearance brings more details into the readers' image of his character. Nick, for example, notices that Gatsby refers to everyone as 'old sport.'
