Answer:
The correct answer is option b. "Use of visual aids".
Explanation:
When a speaker tries to deliver a message to the audience, different styles of receiving the message could be used. The use of visual aids is one technique that has proved to be effective to connect the speaker with the audience regardless of the style of receiving the message selected. Â Presenting graphs, photographs or video clips properly are striking to the audience, and usually last long into the audience memory once the speaker has finished the presentation.
