John received a rough draft of a project outline that he wasn't satisfied with. Which method should he use to convey non-positive feedback?

A. Email

B. Face-to-face

C. Fax

D. Memorandum

The method he should use to convey non positive feedback is though c, fax. It is because this method is sending of a printed material that is scanned which is sent directly to an individual in means of not having to receive any non positive feedback at all as this does not require any reply from the receiver.
