correct answer is a. articulation.
Step-by-step explanation:
The term that involves speaking clearly and distinctly is articulation. Articulation refers to the clarity with which a person pronounces consonants and vowels when speaking. This means that when presenting, you should avoid mumbling or slurring words, ensuring that each sound is pronounced clearly. In contrast, factors like the loudness of speech (volume), how high or low the speaker's voice sounds (pitch), and the speed at which one speaks (rate of speech) will also affect the delivery of a presentation, but they are not directly related to the clear and distinct production of speech sounds.
Articulation is what allows the audience to understand each word and is particularly important in formal settings such as presentations and speeches.
Correct answer is a. articulation.
