Answer:
C. enunciation
Step-by-step explanation:
This is the skill that ensures that the audience understands the words you are saying. Enunciation refers to the ability to pronounce words clearly. A person who enunciates can be understood easily, and the words he utters can all be easily recognized. On the other hand, a person that does not enunciate can be difficult to follow. Ultimately, the most important part of a presentation is the message you are conveying. Therefore, if the words cannot be understood, it can become a serious problem.
