The correct answer is D. Justin avoids eye contact with the board so that they don't feel intimidated. He also doesn't want to take away from the neighborhood's statement so he doesn't mention his relationship with real estate investors.
Step-by-step explanation:
In this situation, Justin needs to communicate his interest in the neighborhood while showing he is an authority in this area by explaining his experience in this field and demonstrating he knows about the topic. In this context, it is ineffective to avoid eye contact because this might be interpreted as a lack of confidence or knowledge. Also, if he does not mention his experience or relationship with real estate investors the audience will not know he is an authority in the field and his ideas are credible. Thus, option D is ineffective for showing credibility and authority.
