Dave Is Consistently Ten to Fifteen Minutes Late to Work

Dave is consistently ten to fifteen minutes late to work every morning. His wife explains to him that this is stealing from his employer. Dave has always considered himself to be an honest person, he therefore justifies the time theft by explaining to his wife that he is not paid enough for the hard work he does so he considers the time part of his salary. Dave changed his attitude in order to justify his actions thereby:

A) fulfilling the prophecy of self
B) averting possible negative reinforcement
C) changing his behaviour to match his attitude
D) reducing cognitive dissonance
