Answer: (C)

The purpose of a definition in communication is to set limits on a word or phrase's meanings. By clearly defining terms, a speaker can ensure that the audience understands exactly what is being discussed. This clarity is essential for effective communication because ambiguous language can lead to misunderstandings and confusion. When a speaker defines concepts, it helps establish a common ground for dialogue and facilitates the audience's comprehension, allowing them to grasp the nuances of the subject matter being presented.

Establishing definitions helps limit the interpretation of ideas, which is especially important in persuasive or informative speech contexts. By precisely articulating what certain terms mean, the speaker can guide the audience's understanding and prevent misinterpretation of the content being conveyed. This strategy is crucial in making sure that the audience engages with the material as intended.
