I know that a theme statement is generally the message or the overall lesson learned of a story or informative essay. So, out of the answer choices given, the complete sentence exploring universal human emotions would not want to be considered for developing the theme, because it mostly has nothing to do with the theme at all.But then again, it may be the statement regarding an individual society, judging on what you are writing about. my opinion is that it is D, but I could be wrong.
