Agoraphobia is characterized primarily by the fear of situations where escape might be difficult or help unavailable in the event of a panic attack or similar symptoms. Therefore, the most relevant choice from your list would be:
- feeling hot and dizzy
This symptom can be associated with anxiety and panic attacks, which individuals with agoraphobia may experience when they are in situations that trigger their fear. The other options do not specifically relate to agoraphobia.
- Losing the desire to work or learn may be related to depression or a lack of motivation but is not specific to agoraphobia.
- Having delusions and hallucinations is more related to disorders such as schizophrenia or severe mood disorders.
- Being scared of heights is a specific phobia (acrophobia) rather than agoraphobia.
So, "feeling hot and dizzy" is the best option related to agoraphobia.
