Which of the following theories have been integrated into a model that suggests genetic vulnerabilities and psychological factors come together to create panic disorder and agoraphobia?

A) Biological and cognitive
B) Cognitive and social
C) Social and biological
D) Psychological and social

The integration of biological and cognitive theories suggests that both genetic vulnerabilities and psychological factors contribute to the development of panic disorder and agoraphobia. Biological factors, such as neurotransmitter imbalances, may make individuals more susceptible to anxiety disorders, while cognitive factors, such as catastrophic thinking patterns, may exacerbate symptoms and maintain the disorder. Therefore, choice A, which combines both biological and cognitive theories, is the best answer.
