From the Perspective of Attribution Theory, in Which Way Are

From the perspective of attribution theory, in which way are teachers' attributions to effort most likely to backfire?

A) When students fail at a task they have tried very hard at and are then told that they did not try hard enough, they may decide they simply do not have the ability to do the task and give up.
B) When students fail at a task they have not tried very hard to succeed at and are then told that they did not exert enough effort, they are likely to feel either embarrassed or angry.
C) When students are told that they did not try hard enough at a task that they expended quite a bit of effort on, they are likely to decide that the subject area has little relevance to their own lives and needs.
D) When students are told that they did not exert enough effort, and they really did not try very hard, they are likely to attribute their failure to an external factor and not accept responsibility for it.
