The answer is the first three. The speaker has a unique imagination so the answer is going to be directed towards the speaker. The first, second, and third answer directly acknowledges how the author sees things differently than everyone else. The other or last two options say what everyone else can see and is therefor not contributing to his imagination.
i dont think there is any reason. you might find that the author has the same themes that he/she likes to write about but idk i think you need to read the book
