Answer:
D) Specific objections to your proposal.
Explanation:
If you are going to give a presentation to an audience you consider hostile, it is best to research what they think about the topic of your speech. This way you can better prepare to answer any questions, objections and questions. For example, if you are going to give a talk to experts on a topic, you can read the articles they wrote about that topic that are contrary to your point of view. This way you will know what they think about your topic and can predict what they tend to question. So you get ready for it and you can do well in the lecture.
