Which appeal indicates that customers are worthy of a fulfilling life according to the speaker?

The choice indicating that customers are worthy of a fulfilling life aligns with the idea of avoiding any sort of manipulation in the way information is presented. When a message is constructed without employing dubious techniques, it suggests a focus on integrity and earnestness, thereby framing the customers as deserving individuals who can make autonomous choices. This perspective fosters a trustful relationship between the speaker and the audience, emphasizing their inherent worthiness and reinforcing the notion that they are capable of leading fulfilling lives based on their own decisions rather than through coercive or misleading tactics.

In contrast, the other methods of persuasion such as assertion, appeal to authority, and appeal to practical consequences employ more direct strategies that might not underpin the fulfillment of life theme in the same way. They are more concerned with making claims, relying on the credibility of sources, or focusing on the results of actions rather than on the intrinsic value of the customers as individuals capable of achieving their own fulfillment. The approach under the correct choice emphasizes the respect for the audience's ability to discern and choose, reinforcing their worthiness in a manner that resonates with the overall message of valuing life and self-fulfillment.
