Fill in the blank ______ is also the only antipsychotic that has been documented to reduce the risk of suicide in schizophrenia and may have a particular niche in treating aggression and violence in psychotic patients.

A. Risperidone: Risperidone is effective for treating positive and some negative symptoms of schizophrenia but has not been shown to reduce suicide risk. Its primary benefits are symptom control rather than addressing suicidality or aggression. B. Clozapine: Clozapine is the only antipsychotic with strong evidence for reducing suicide risk in patients with schizophrenia. It also demonstrates efficacy in managing aggression and violent behaviors, due to its unique receptor profile and modulation of dopamine and serotonin systems. C. Quetiapine: Quetiapine is useful for mood stabilization and psychosis but lacks documented effects on suicidality or violent behaviors. Its primary niche is in treating bipolar depression or as an adjunct in unipolar depression rather than high-risk aggressive psychotic patients. D. Aripiprazole: Aripiprazole is generally well tolerated and effective for positive and negative symptoms but does not have proven anti-suicidal effects. Its partial D2 agonist activity helps with metabolic profile but does not confer the unique anti-aggression or suicide-reducing benefits of clozapine.
