The Testimonial in the Mock Site for Deep Mind Therapy

The testimonial in the mock site for Deep Mind Therapy (DMT) about how DMT helped a man get in touch with his unconscious mind provides:

A) good support for DMT, because it is the personal experience of someone who has been treated with DMT.
B) no support for DMT, because it is not an argument in the strict sense.
C) questionable support for DMT, based on untested assumptions about the unconscious mind.
D) good support, because Jung studied with Sigmund Freud, who was an expert on the unconscious mind.
