Answer: B: Block dopamine receptors in the brain 
Explanation: All antipsychotic agents except rauwolfia alkaloids block dopamine receptors in the brain. Locus coeruleus is the site of most noradrenergic neurons in the brain. The dopaminergic neurons in the brain are primarily found in three areas ;the basal ganglia (nigrostriatal tract), the midbrain (mesolimbic tract), and the hypothalamus. Ref: Nurnberger, Jr. J.I.
