A、She makes good use of an ad to convince her father. B、She has enough money to buy Adidas shoes herself. C、She wants her father

W: Dad!
M: Yes? What’s the matter, Krista?
W: I’m wondering if I should buy a pair of tennis shoes. I’m going to join the tennis club in school.
M: Why not? It’s good that you finally play sports.
W: But I’d like to have Adidas.
M: Adidas? It’s expensive. It’s for the Chicago Bulls!
W: No. All the guys on the school tennis team are wearing Adidas, boys, as well as girls...
M: But none of us has ever had Adidas and we used to play quite OK.
W: Here, Dad, is an ad about Adidas. Can I read it to you?
M: Go ahead.
W: "Over forty years ago, Adidas gave birth to a new idea in sports shoes. And the people who wear our shoes have been running and winning ever since. In fact, Adidas has helped them to set over 400 world records in track and field alone."
M: Nonsense! The players have to go through a lot of hard training and practice. It’s nothing to do with the shoes. They may be comfortable, but...
W: You are right, Dad. The ad goes on to say "You are ham to run. And we were ham to HELP YOU DO IT BETTER."
M: Hmm. Maybe good for running, but you don’t run.
W: Listen, "...Maybe that’s why more and more football, soccer, basketball and tennis," see? "TENNIS players are turning to Adidas. They know that, whatever their game, they can rely on Adidas workmanship and quality in every product we make."
M: OK, OK, dear. I know Adidas is good. But how much is a pair of your size?
W: You don’t have to worry about that, Dad. I’ve saved some money since last Christmas. I just want to hear your opinion.
M: That’s good. I have been wanting to have a pair of Adidas sneakers myself.
