The Correct Answer is:
B. Childhood is a time to learn life lessons.

In the story A Tree Grows in Brooklyn by Betty Smith the main character learns about a life lesson about when telling people things to tell them how it actually happened but when she was writing she could write it the way that she thought it should have happened.
