Answer: B. A phobic disorder
Explanation: A phobic disorder is generally the fear of something, an event, a situation, someone, etc. Then there is an exaggerated and irrational fear that, therefore, has no foothold in reality, and the person suffering from this disorder persistently fears based solely on phobias. These phobias may be different, for example an indoor phobia, but also the open space phobia, the crowd in the street, being stuck in an elevator and the phobia of lack of air, etc. can also be a reason. A characteristic of a phobia is an anxious feeling that can be experienced even at the very thought of a phobia, therefore, without experiencing any of the situations that cause the phobia, the very thought of them is the cause of anxiety.
