Answer:
The correct answer is Their brain is not yet fully developed and they sometimes make the wrong choices.
Step-by-step explanation:
There is an explanation for how teenagers act regarding decision making and this is due to the maturation of their brain.
Teenagers' brains have not reached the highest level of development, just like adults.
The area of the brain responsible for making us distinguish between "good and evil" and the one that helps us make decisions is the frontal area, and scientists have found that during adolescence this area of the brain has not developed, but that It does completely in the adulthood.
That is why teens tend to make bad decisions.
