Using the following report,which audience segment might the campaign manager choose to remove from their targeting approach?

The campaign manager might remove "LS-Parents with Children in Household" because the report shows this segment has a significantly higher Cost Per Mille (CPM) and a lower Click-Through Rate (CTR) compared to the other options. A high CPM means it's expensive to reach this audience, and a low CTR indicates they are not engaging with the ads effectively. This combination suggests poor return on investment. "LS-Sci-fiInterest" and "IM-Exercise&Fitness Apparel" likely have more favorable CPMs and CTRs, indicating they are more efficient and effective segments for targeting, and therefore should be retained.
