Answer:
C. Investors made 5 percent more with our app than with the leading app.
Step-by-step explanation:
This sentence presents a logical comparison of the performance of two apps based on a specific metric, which is the percentage of profit made by investors. It appeals to logic and reason by using concrete data (5 percent more) to support the claim that the app being promoted is more effective than the leading app in terms of financial returns. This is an example of a logical argument based on evidence, which is a characteristic of logos, one of the three rhetorical appeals or modes of persuasion, along with ethos (credibility or ethical appeal) and pathos (emotional appeal).
