Explanation:
'Logos', one of the modes of persuasion as offered by Aristotle that focuses on logic or reason to convince the readers to believe in a particular idea, thought, or claim presented by the author. The purpose is to appeal the readers logically or reasonably by offering facts or statistics to establish the credibility of the claim and persuade the readers to accept a particular idea.
As per the question, option B employs logos as it proposes a logical appeal substantiated through facts like 'All of the other schools in our district offer organic foods in the lunchroom' and persuade the audience to accept and count on the claim proposed 'our school should offer organic foods as well'. Thus, <u>option B</u> is the correct answer.
