The correct response is: "because the prefrontal cortex is not done being rewired yet."
During adolescence, the prefrontal cortex, which is responsible for higher-level cognitive functions such as planning, decision-making, and impulse control, is still developing and undergoing significant changes. In contrast, the amygdala, which is involved in emotional processing and responses, is more mature at this stage, leading to a stronger influence of emotions on decision-making in teens compared to adults.
