The correct option is b) The amount of background information you give your audience should vary depending on what your audience already knows about your topic.
Step-by-step explanation:
The amount of background information you should give your audience about your topic varies depending on what your audience already knows. You need to assess their prior knowledge and relationship with the topic to determine the right amount of context to include. For an audience new to the topic, you should provide necessary background information to help them understand.
On the other hand, with a knowledgeable audience, background information should be covered quickly to avoid redundancy. It's crucial to present this information in a way that is relevant and enhances the audience's understanding of the subject, which often includes anecdotes, location placement, and factual evidence. This approach ensures that your writing is adjusted to the audience's needs, providing a logical structure and establishing credibility.
