You’d like to further break down and analyze the data shown in a standard table report. Which feature would you select to do that?

Secondary Dimension" allows you to add another dimension to a standard report table, breaking down the existing data by an additional attribute. For example, if your primary dimension is "Country," you could add "Device Category" as a secondary dimension to see traffic from each country further categorized by desktop, mobile, or tablet. "Comparisons" lets you compare different segments of your data side-by-side, but doesn't add a new dimension to the existing table structure. "Breakdowns" is not a standard feature name in Google Analytics for this function. "Filters" are used to narrow down the data displayed in a report, not to add new dimensions for analysis.
