Raquel is looking to use her current audience to reach more people. What could she do?

Enabling Audience Expansion is the correct choice because it allows LinkedIn's algorithm to identify and target users who share characteristics with your existing audience but are not explicitly included in your current targeting. This effectively broadens your reach to new, relevant prospects. Using the Manual Bid option, setting more competitive bids, or increasing your daily budget are all strategies related to optimizing ad delivery and visibility within your existing target audience, not to expanding that audience to new users. While these can improve performance, they don't directly address the goal of reaching more people beyond your current audience in the way Audience Expansion does.
