Answer:
C). By providing supporting evidence of a prince believed to be clever because he chose a good servant.
Step-by-step explanation:
Text structure plays a vital role in conveying the intended message or idea effectively to the audience as it emphasizes organizing the various elements of the text in a manner(cause and effect, compare-contrast, problem-solution) that assists them(readers) in understanding the text clearly and comprehensively.
The given passage from 'The Prince', the author provides 'supporting evidences to substantiate the central idea of Prince of Siena, Petrucci being judged by his servant.' The author logically elaborates that the prince was not considered clever as he has Venafro as his servant and his intellect is determined by his ability to find good and bad in his servant. Thus, he ensures that he remains loyal and does not deceive him. Therefore, option C is the correct answer.
