This question refers to the story "The Stolen Party" by Liliana Heker.
Answer:
The correct answer is option B. It causes Rosaura to disagree with her mother.
Step-by-step explanation:
Rosaura has a disagreement with her mother because she wanted to go to Luciana's party, but her mother did not want to.
She said it was a party for rich people and that she was just the maid's daughter.
This caused Rosaura to get angry, as she considered Luciana her friend and decided to go to the party anyway.
