Answer:
A. The listener: understanding their position, and tailoring your strategy accordingly, is more persuasive.
Step-by-step explanation:
In business, the more you talk, the less persuasive you become. Keeping quiet and choosing your words shows integrity, and by staying quiet rather than trying hard to persuade makes you more able to achieve your goals. As the more the other talks, the more you gain the upper hand in the matter of pressuring the other to your higher benefit.
