After enrolling in the MBA program at Minor State University, Sheri began having second thoughts. Although MSU seemed to be a good choice based on location, reputation, and price, Sheri was not convinced she had made the right choice. Sheri is suffering from:
a. too many opportunity costs. b. dissatisfaction. c. choice insufficiency. d. cognitive dissonance. e. poor product quality.

Option D                  

Explanation:

In simple words, Cognitive dissonance refers to the practical contact of mental stress that arises whenever an individual holds two or more contradictory beliefs, ideas, values or takes part in a behavior contrary to some of these three.

As per this concept, when two acts or thoughts do not coincide mentally with each other, individuals will do everything they can to alter these until they become compatible.

Thus, from the above we can conclude that the correct option is D .
