A directional hypothesis makes a specific prediction about the direction of an effect, in this case, that students who receive performance-based assessments will score lower on a test of problem-solving skills compared to those who do not receive performance-based assessments. B is a non-directional hypothesis because it only states that there will be a difference in scores but does not predict the direction of the effect. C is a null hypothesis because it predicts no difference between groups.
