Which Is True About the Abnormalities in the Frontal-Striatal Neural

Which is true about the abnormalities in the frontal-striatal neural circuit in youths with ADHD?

A) A longitudinal study has indicated that the frontal-striatal neural circuit in youths with ADHD develops more slowly, by about 3 years, than it does in typically developing children.
B) By adolescence, the growth of the frontal-striatal neural circuit in those with ADHD has caught up to their peers'.
C) Youths with ADHD show too little dopamine in the striatum and too much dopamine in the right prefrontal cortex compared to typically developing peers without ADHD.
