A. The owner of the store treats her disrespectfully.
Explanation:
There lived a girl named Neddy. She lived in a small house with her parents and brothers. The house was small and had a narrow staircase.
There was a junk store near the girl's house. It was owned by an old black man. The man will not treat the customers well until he knows they have enough money.
One day the girl asked him about a pretty musical box. The man refused to sell it to her.
Both the girl and the owner are enticed by the music played and the music calms their mind.
