您合作的一家服装经销商推出了新款围巾系列。他们正在移动网络和移动应用内广告资源中投放广告。如果他们想查看新品在这两个平台上的交易数量，您应当为他们运行下面哪个报告？

The correct answer is "即时报告" (Instant Report) containing "总转化次数" (Total Conversions). An Instant Report provides a quick, real-time overview of key metrics, including total conversions, which directly answers the client's need to see the number of transactions across mobile web and in-app platforms. "覆盖面报告" (Reach Report) with "展示覆盖面" (Impression Reach) focuses on unique users exposed to ads, not conversions. "多设备报告" (Cross-Device Report) with "跨屏转化" (Cross-Device Conversions) is designed to show conversions across different devices, not specifically for mobile web versus in-app within the same device type. "转化路径报告" (Conversion Path Report) with "总收入" (Total Revenue) analyzes the sequence of interactions leading to a conversion and revenue, which is more detailed than simply counting transactions.
