Answer:
A. a clear message and positive ethos
Step-by-step explanation:
Clarity in communication refers to being effectiveness in conveying the intended message. Clarity in speech is a must for any speech as it aids in better comprehension of the message by the listener.
Ethos refers to the creation of authority and command in speech. It also refers to whether the speaker is able enough to speak on a subject or is he the right person to speak on such a matter.
Through ethos, the speaker establishes his command over the subject he has chosen to speak upon.
Positive ethos would mean displaying a positive body language while speaking and maintaining calm and open to questioning and providing the required response. It refers to building an amiable rapport with listeners.
