Answer:
It is chronological, written in 3rd person. The other answers are on the explanation.
Explanation:
1984 is a book written by English author George Orwell. The book tells the story of a parallel world (dystopian), focused on the main character, named Winston Smith, and how he develops himself surrounded by a hostile environment.
It is structured in chronological order, meaning that the events happen one after another in a linear time. This is the way 1984 is narrated, since the narrator does not go back and forward to tell the story.
As we can see, 3rd person was chosen as the point of view, since the reader does not see all the story from Smith's point of view, which would be first person POV. The narrator focus on aspects from the story that can make the reader feel overwhelmed, since the narrator mentions how big or impressive things or people are.
The meaning of the novel is enriched by this point of view by several reasons. If the narrator were focused only on Winston Smith's perspective, readers could understand it as his very personal story. However, according to the publication context, perhaps Orwell wanted to do something different. We can see that by looking at the name of the main character. Since both name and last name are very common in England, both perspective and names mean that it could happen to anyone, anywhere.
