Saks' Argument About Dissociative Identity Disorder as an Insanity Defense

Saks' argument about dissociative identity disorder as an insanity defense is that

A) the body who commits the crime should be held responsible,regardless of whether the "person" was conscious of the crime being committed.
B) the person,not the body,is responsible for a crime.
C) dissociative identity disorder is usually faked by criminals pleading insanity and thus should not be an allowable defense.
D) since therapy for dissociative identity disorder is not usually effective,confinement to a prison mental hospital is illogical.
