The correct answer is A.
Hally is a seventeen-year-old white boy who has a poor relationship with his parents. His father is an alcoholic and his mother is too submissive to stand up to her husband.
Sam is a black man that works as a waiter in the St. George's Park Tea Room. He is compassionate man who really gets Hally's problems with his family and truly cares for him.
Sam's goal in life is to help Hally grow into someone who is proud of himself, and that is why he builds him the kite.
