Be more specific so I can help you
A coma like state which may alternate with periods of agitation is very likely to be diagnosed as comatose schizophrenia.
Schizophrenia can be a hard disease to diagnose and for that reason, the comatose subtype can be ever harder to diagnose sometimes.
Just macroanatomy right?
I would say A, as the only answer.
Hope that helps,
