Correct Response: A. A manager seeking to encourage interaction and open the lines of communication between employees should conduct a short meeting to invite employees to contribute and participate in discussions. Physical presence allows for face-to-face interaction and collaboration. Although a phone call is a personal way to convey a message (B), it does not offer the convenience or option for others to contribute. E-mail communication is fast and efficient and group messaging is easily accomplished, but it does not invite interaction (C). A presentation is typically a one-way communication from the presenter to the audience, and while questions from the audience are often encouraged, a presentation does not promote collaborative or interactive communication (D).
