People with generalized anxiety disorder:

A) suffer from persistent anxiety that cannot be attributed to a phobic object, situation, or activity.
B) show absence of autonomic arousal that leads to anxiety attacks.
C) are typically afraid of suffocation.
D) have extreme mood swings from ecstatic elation to deep depression, including suicidal tendencies.

Generalized anxiety disorder is characterized by persistent and excessive worry and anxiety about everyday events and activities, not tied to a specific phobia or trigger. Autonomic arousal may still be present, but it is not the primary factor causing anxiety. Fear of suffocation is not a specific symptom of generalized anxiety disorder, and extreme mood swings are not a common feature.
