  answer:D)oppositional defiant disorder.he is simply defying authority figures.if it were C)conduct disorder,he would have exhibited other signs like cruelty to animals,drug abuse,fights in school,destroy property,etc.the problem is for the past he doesnt have E)reading disorder,since he was normal prior to that.F)normal adolescent behavior could be a possibility,but he was 10years old when the problem first started.A)ADHD is eliminated,because he is not hyperactive.he is simply uncooperative and rolls his eyes during physical examination,he is not fidgety.B)borderline cognitive behavior=borderline personality disorder,where patients classify the world into positive and gray shades.
