Helena wants to compare the performance of ads running on owned and operated sites to ads running on the Microsoft Search Partner Network. In which of the following ways can Helena do this?

To compare ad performance between owned/operated sites and the Microsoft Search Partner Network, Helena should use the "Segment" feature and select "Network." This allows her to break down her campaign data by the specific network where the ads appeared, providing a direct comparison of metrics like impressions, clicks, and conversions for each network. "Dimensions" is used for broader data analysis, not for segmenting by network type. "Top vs. other" is a segment option that distinguishes between ads appearing at the top of search results versus other positions, which is not relevant to comparing owned sites versus partner networks.
