What causes the conflict between the characters in this passage?

D. The mother believes that her daughter is not trying her best, and the daughter disagrees.

Explanation:

“Well, I probably can't play anymore,” I said. “It's been years.”  

“You pick up fast,” said my mother, as if she knew this was certain. “You have natural talent. You could been genius if you want to.”   “No, I couldn’t.”   “You just not trying,” said my mother. And she was neither angry nor sad. She said it as if to announce a fact that could never be disproved. “Take it,” she said.
