I need the sentences because I can't help you without them I'm very good with English.
Key words would be the best :)
<span>C. "Recent studies have shown that people who exercise live longer than people who do not. Come try our new exercise program. Free one-month trial."
This appeals to logic because it is stating information that is "proven" (based on whatever this study was), which will get people thinking less emotionally and more logically about the benefits.</span>
Its probably B. its literally in the sentence <span />
