According to cognitive dissonance theory,dissonance is most likely to occur when

A) a person's behavior is not based on strongly held attitudes.
B) two people have conflicting attitudes and find themselves in disagreement.
C) an individual does something that is personally disagreeable.
D) an individual is coerced into doing something that he or she does not want to do.

Cognitive dissonance theory holds that dissonance arises when an individual's behavior conflicts with their personal beliefs, values, or attitudes. Therefore, when an individual does something that is personally disagreeable to them, dissonance is most likely to occur. Choices A, B, and D do not necessarily involve personal beliefs, values, or attitudes being conflicted, and thus are less likely to result in cognitive dissonance.
