Which of the following, according to Aristotle, will contribute to a communication's credibility?

For Aristotle, a communication's credibility grows from goodwill, trustworthiness and wisdom, the qualities of character that make an audience believe the speaker.

Statement 3, goodwill, shows the speaker means well toward the listeners and seeks their interest.

Statement 4, trustworthiness, marks the speaker as honest and dependable, worth taking at their word.

Statement 5, wisdom, gives the speaker sound judgement and good sense that lend weight to what is said.

Personal appearance rests on outward looks rather than the inner character Aristotle tied to credibility.

Peculiar mannerisms are surface habits that, if anything, distract from the ethos that persuasion depends on.
