After Reviewing the Results of the Follow-Up Research Conducted by Manfred

After reviewing the results of the follow-up research conducted by Manfred Bleuler, what conclusion could we reach concerning the outcome of schizophrenia?

A) The long-term prospects for people with this disorder remains dismal in most cases.
B) About half of those diagnosed with schizophrenia will either recover or exhibit at least some improvement.
C) Contrary to general opinion, schizophrenia is more of an episodic disorder from which recovery rates tend to be quite high.
D) The deterioration that occurs in schizophrenia is not reversible, and consequently few, if any, people will make any meaningful recovery.
