What time unit breakdowns are available for campaigns with custom reporting?
- Daily only
- Summary, daily, day-of-week, monthly, weekly (Sunday to Saturday)
- Daily, day-of-week, and monthly
Explanation: The selected answer **Summary, daily, day-of-week, monthly, weekly (Sunday to Saturday)** is correct because custom reporting in Amazon Ads allows for a variety of time unit breakdowns to be applied, offering flexibility in how campaign performance is analyzed. These breakdowns include the summary view for an overall performance overview, daily data for tracking campaign progress on a per-day basis, day-of-week data to analyze performance trends across different days of the week, monthly data for a broader view over time, and weekly data (from Sunday to Saturday) to understand performance patterns across entire weeks. This range of breakdowns provides advertisers with detailed insights to optimize their campaigns based on different time perspectives.
