Solution

The answer is the third one (3): dopamine.

Explanation for each option:

GABA: Gamma-aminobutyric acid (GABA) is primarily an inhibitory neurotransmitter in the brain. While it plays a role in anxiety and mood disorders, it is not the primary target for treating psychotic disorders like schizophrenia.
Serotonin: Serotonin is involved in mood regulation and is a target for antidepressants and some antipsychotics. However, blocking serotonin alone is not the primary mechanism for treating psychotic disorders.
Dopamine: Dopamine is a key neurotransmitter involved in the pathophysiology of schizophrenia. Many antipsychotic drugs work by blocking dopamine receptors, particularly the D2 receptor, which helps alleviate symptoms of psychosis.
Epinephrine: Epinephrine, also known as adrenaline, is more involved in the body's fight-or-flight response and is not a primary target for treating psychotic disorders.

In summary, drugs that block dopamine receptors have been shown to be an effective treatment for psychotic disorders like schizophrenia.
