The concept of organization and intentionality is missing from this definition of public speaking, according to the textbook. Thus the correct answer is A and B.
<h3>What is the definition?</h3>
The definition is referring to any statement which defines or explains the complete meaning of any word in the elaborative form to make it clear to the reader in an easier manner.
The given statement "a face-to-face attempt to inform, persuade, or entertain a group of people through words, physical delivery, and visual or audio aids." eliminates the concept of intention and organization which creates confusion in understanding the meaning of public speaking.
Therefore, option A and B is appropriate.
