The correct answer is third person objective. This kind of narrator tells a story without describing any character's thoughts, opinions, or feelings; in its place, it gives an impartial, unbiased point of view. East of Eden is narrated in third person by Sam Hamilton's grandson, who is in fact a fictionalized John Steinbeck. The narrator is not omniscient but gives commentary on the events of the novel, often stopping to make general, common truth-type statements. The narrator of the story is a real character who is reflecting on the lives of the previous generations which enhances a more personal tone to the story.
