Which statement best reflects the medical model

A)  All physical illnesses have a psychological component. 
B)  Abnormal behaviour can be thought of as a disease. 
C)  All mental illnesses are caused by biological factors. 
D)  All mental illnesses can be treated using drugs.

The medical model views abnormal behaviour as a disease that can be diagnosed and treated just like physical illnesses, which aligns with option B. Option A is incorrect because not all physical illnesses have a psychological component. Option C is incorrect because there is evidence to suggest that mental illnesses can be caused by a complex interaction of biological, psychological, and social factors. Option D is incorrect because while drugs can be an effective treatment for some mental disorders, it is not the only or always the best treatment option.
