B. It's not a plot summary because it's just a little tip and contains no plot summary in it.
Answer: B) It states a universal truth about life.

Usually this belief, or idea, is universal and transcends cultural barriers. So, the given statement is considered a theme (and not a plot summary) because it states an universal truth about life (the correct answer is option B).
