A) a danger signal that repressed conflicts are threatening to surface.
B) a learned reaction.
C) the result of illogical, irrational thought processes.
D) linked to an imbalance in several neurotransmitters in the nervous system.

The biological perspective suggests that generalized anxiety disorder is linked to an imbalance in several neurotransmitters in the nervous system. This can include lower levels of serotonin and gamma-aminobutyric acid (GABA), which are both involved in regulating anxiety. Additionally, research has found that individuals with generalized anxiety disorder may have abnormal activity in certain areas of the brain, such as the amygdala, which is involved in processing and responding to threats.
