There are lots of rumors going around about Gatsby. Some people say he is a spy and others say he once killed someone. The truth is a bit simpler than that: Gatsby was born into a poor farming family. He had to work to put himself through college.
These rumors, as well as Gatsby's reality, illustrate the theme of illusion vs. reality. In this world, nothing is as it appears to be. Everything is an illusion -- everyone is pretending to be something they're not.
In this, Gatsby is no different. Many characters, Gatsby included, wear a mask that hides the real person underneath.
The author is making the point that the world of glitz and glamour is often all for show.
I looked through the choices, and from the first glance I could cancel out B. and C. Because those two have nothing to do with this kind of story. So now we are left with A. and B. A myth is a traditional story, especially one concerning the early history of a people or explaining some natural or social phenomenon, and typically involving supernatural beings or events. So you can't use that, so <em>the answer should be D. Hope that helped.</em>
Answer is D. Indirect subject.
