Final Answer :
B
Explanation :
Research has shown that the catecholamine neurotransmitters, which include dopamine, serotonin, and norepinephrine, function abnormally in individuals with ADHD. The prefrontal cortex, which regulates attention, organization, and planning, has been found to be smaller in volume and show abnormal activation in children with ADHD. The notion that hyperactivity in children is caused by dietary factors has not been substantiated in controlled studies. There is no significant association between ADHD and birth weight.
