Answer:
Cognitive dissonance
Explanation:
Cognitive dissonance: In psychology, the term cognitive dissonance is referred to as the phenomenon in which an individual feels discomfort due to the mismatch between his or her beliefs and behavior or when he or she encounters a piece of new information.
In other words, it involves conflicting beliefs, behaviors, or attitudes that an individual holds.
Factors that lead to cognitive dissonance include personal cognitions, disparity between belief and conflicting thoughts, etc.
In the question above, the statement signifies the concept of cognitive dissonance.
I think that the key point here is the "easily reproducible" - because all of them can be scientific questions (even a! it could tell us about about the human psyche!)
but d. is the best answer for a reproducible experiment. B could also make a good experiment, but it would be too expensive to be easily reproducible. C is calling for a more complex analysis that is too complex for an experiment. And a would require more questionnaires than experiments
