Answer:
B. Only the rich could afford to pay for therapy.
Step-by-step explanation:
In 1900 social inequality was much more prominent than today. Poor people had little or no access to quality medical treatment or any medical treatment because the prices were too high. With regard to treatment of psychological illnesses the prices were even higher, as treatments were scarce and few professionals knew what to do. The result is that only rich people had access to therapeutic treatments because only these rich people could afford it.
