The correct answer is B. Self-fulfilling prophecy.
Explanation:
In psychology, the self-fulfilling prophecy occurs as one's behavior, ideas or results match those predicted by someone else because we have believed those predictions. This phenomenon occurs in the case of positive predictions, but also in the case of negative predictions. This applies to Daniell because due to her teacher predicting Daniell was not going to perform well in class, Danielle does not try very hard and thus, she fulfills the negative prophecy of the teacher as she has believed she was not going to perform well.
