Keep in mind that an author’s/a writer’s “tone” is basically their mood, attitude or stance upon the topic they’re writing about. (An easy way to remember that: you know how sometimes parents say to “watch your tone” when you say something back to them? Remember that when you’re looking for an author’s tone: you’re looking for a mood or attitude.)
The correct answer would most likely be D, because complexity wouldn’t really be important when looking for a tone within text.
