Dr Samuel Cartwright's Diagnosis of Drapetomania, Which Purported to Explain

Dr. Samuel Cartwright's diagnosis of drapetomania, which purported to explain why slaves sought freedom, exemplifies:

A) recognition of panic disorder as far back as the early years of the nineteenth century.
B) how notions of mental disorder can serve the interests of those who are in power by putting a veneer of science on a subjective process.
C) the recognition of the intolerable conditions of slavery and the need to escape those conditions.
D) how great suffering elicits the "fight-or-flight" response, which is a normal human reaction.
