B. require readers to read between lines to understand the entire meaning.
Explanation:
Persuasive messages are used to engage, involve and induce the recipient to make a decision. They often present a dichotomy between reason and emotion (ethos and pathos): If the message totally lacks emotion and only presents information straight away, it won't be attractive for the recipient. On the other hand, if the message is totally focused on emotion and information is insufficient, the recipient will find it scarcely credible. Thus, there has to be a balance between reason and emotion.
