The correct answer is:
C. passions.
Adolescents are known to experience intense emotions and passions, but their prefrontal cortex, the part of the brain responsible for decision-making and impulse control, is not fully developed during this stage of development. As a result, while they may have strong emotions, their ability to regulate and control these emotions may still be developing. This can lead to impulsive behavior or difficulty in managing their passions effectively.
