The correct answer is C. A face-to-face meeting
Step-by-step explanation:
A face-to-face meeting is one of the most common communication forms used in business, this implies participants meet in the same space and at the same time and therefore interaction occurs directly. This type of interaction is more beneficial than email messages, telephone conversation or voice mails in terms of understanding both the verbal and non-verbal information.
Indeed, only in a face-to-face meeting, you can see the gestures, movements, and position of the other person which often reveals more than his/her words. Due to this, Steve should use a face-to-face meeting because this channel would allow him to gather more information than other channels as it is the only one that would allow him to understand nonverbal cues.
