Which of the following best represents an appeal based on practicality in advertising?

The choice that best represents an appeal based on practicality in advertising is the comparison of delivery costs and time. This option focuses on providing consumers with specific, concrete information that can affect their decision-making process. Practicality appeals to an audience's logical side by presenting clear benefits such as cost savings and efficiency, which are critical factors for many consumers when making purchasing decisions.

In contrast, other options focus on emotional appeals or less tangible benefits. A political ad highlighting educational funds might evoke feelings about social responsibility but does not offer immediate practical advantages in a consumer context. A personal anecdote about feeling alone touches on personal experiences and emotions but lacks concrete practical implications for a product. Finally, a description of a luxury item may attract consumers seeking status or prestige, but it doesn't address practical considerations, which are often more compelling for budget-conscious or utility-driven buyers.
