C. Dopamine, glutamate, and histamine are associated with anxiety in some way
D. Only acetylcholine is associated with anxiety
E. Anxiety can be treated with injection of epinephrine

Answer 1

Statement B is correct; neurotransmitters such as GABA, norepinephrine, and serotonin are all associated with the regulation of anxiety.

Step-by-step explanation:

The correct answer to the question of which statement is true regarding neurotransmitters and anxiety is B. GABA, norepinephrine, and serotonin are associated with anxiety in some way. Gamma-Aminobutyric Acid (GABA) is the main inhibitory neurotransmitter in the central nervous system, which helps regulate anxiety. GABAergic transmission often has an inhibitory effect that can help counteract anxiety, and drugs that act as GABA agonists, like benzodiazepines, are known to have anxiolytic effects. Norepinephrine and serotonin are also involved in the regulation of mood and anxiety, with imbalances in these neurotransmitters being linked to anxiety disorders.
