Your aunt has a fear that makes it difficult for her to leave her home. She feels trapped and is unable to work or engage in any kind of activity that requires going outside of her home. You are not surprised when you find out your aunt is diagnosed with _________________.

A) trypanophobia
B) odontophobia
C) agoraphobia
D) a specific phobia

Agoraphobia is a fear or anxiety about being in situations or places where escape might be difficult or embarrassing in case of a panic attack or other symptoms. This fear often leads to avoidance of situations such as leaving home, using public transportation, or being in crowds. This description matches the symptoms described for the aunt in the scenario, making agoraphobia the best choice. The other options, trypanophobia and odontophobia, refer to specific fears of needles and dental procedures, respectively, and would not explain the aunt's broader fear of leaving her home. Option D, a specific phobia, is a general term for specific and often irrational fears of specific objects, situations, or activities, but agoraphobia is a specific type of phobia related to particular situations.
