Which narrator is most clearly omniscient?

The third-person omniscient point of view is the most objective and trustworthy viewpoint because an all-knowing narrator is telling the story. This narrator usually has no biases or preferences and also has full knowledge of all the characters and situations. That makes it very easy to give lots of supporting details about, well, everything.

I can't really see the question or the options.. but hopefully I helped in some way! :)
