Answer:
b. “Laetitia had a lot of pride, and so did my mother.”
Step-by-step explanation:
In "Borders," Mother is Blackfoot, and she does not identify with any other identity. When she wants to cross from Canada to the United States, she is asked about her nationality, but she refused to claim that she is anything other than Blackfoot. She is so proud of this that she decides to sleep in the car rather than give up. This shows the importance that such an identity has for her.
