The paragraph emphasizes RD Laing’s criticism of conventional psychiatric treatments and the psychiatric establishment, especially in how it treats individuals labeled as "schizophrenic". His focus was on the ethics of human interaction and critiques of institutional practices.
Option (B) best reflects this focus — it states clearly his opposition to inhumane psychiatric practices like electric shock treatment.
While Options (A), (C), and (D) describe related or plausible views of Laing, only (B) directly captures his documented criticism of established psychiatric methods as stated in the paragraph.
