Option C is the correct smart list section for their data management smart campaign. This option uses the Visits Web Page trigger with the Min. Number of Times constraint set to 3 and the Date of Activity constraint set to in past 90 days. This will ensure that only people who have visited any web page at least three times within the last 90 days will qualify for the campaign. Option A uses filters instead of triggers, which means that it will not run automatically and instantaneously. Option B uses an incorrect filter logic, which means that it will not require three web page visits within 90 days
