C, It helps the reader see a truth about life
Step-by-step explanation:
The reason the answer would be C is because A, B, and D are proven to be incorrect through process of elimination. . It is not clearly stated in the story because the author wants you to dig deep and read the story to develop a higher understanding. It won't necessarily be a one or two word phrase because usually a theme is developed throughout the whole book and can flucuate depending on how the reader envisions the story. It is not to create suspense either it is to teach you a lesson and help you learn something new about life.
