A person is sweating, experiencing shortness of breath, choking, feeling dizzy, and afraid of dying. Assuming this event is not a heart attack, but rather an indicator of anxiety disorder, it is MOST likely a:

A) panic attack.
B) phobia.
C) obsessive-compulsive response.
D) posttraumatic disorder.

These symptoms are characteristic of a panic attack, which is a sudden episode of intense fear that triggers severe physical reactions when there is no real danger or apparent cause. Panic attacks can be very frightening and can include symptoms like sweating, shortness of breath, feelings of choking, dizziness, and fearing death, distinguishing them from the specific symptoms or triggers associated with phobias, obsessive-compulsive disorder, or post-traumatic stress disorder.
