Which of the following is true of a deductively organized message?

A) It uses a buffer or goodwill opening to soften the approach and the reader's reception.
B) It starts with a direct introduction followed by a brief overview of the contents of the message.
C) It starts with an explanation and details followed by the main idea of the message.
D) It announces the purpose of the message from the sender's perspective.

A deductively organized message starts with a direct introduction that lays out the main point or conclusion, followed by a brief overview of the supporting reasons or details. This approach is most effective when the reader is likely to agree with the conclusion and needs only a little persuasion to take action. It is also useful when presenting complex or technical information, as it allows the reader to quickly grasp the main point before delving into the details.
