I believe the answer is: B. cognitive dissonance 

Cognitive dissonance refers to a situation when people experience inconsistency in their principles/belief. Cognitive dissonance is much more common among people in younger age compared to the older age group because younger people tend to still haven't developed a solid principles/belief due to lack of exprience.

It would be (b.)
