MY ANSWER IS C

I agree.

Your answer C is correct. In the latter part of the 1880s, psychiatrists and neurologists tended to believe that madness was caused by biological troubles in the brain and troubles in the nervous system. Less severe syndromes like hysteria were also believed to be caused by these same factors.

Your answer is correct. In the latter part of the 1880s, psychiatrists and neurologists tended to believe that madness (referring to serious mental disorders) was caused by biological troubles in the brain and also troubles in the nervous system. They viewed these disorders as primarily rooted in physiological abnormalities rather than psychological or environmental factors. Additionally, less severe syndromes like hysteria were also attributed to similar biological troubles in the brain and nervous system. So, option C, "biological troubles in the brain, troubles in the nervous system," accurately reflects the prevailing belief at that time. Well done!
