一家全国性宠物食品店正在桌面设备、手机和平板电脑上投放一个广告系列。他们想要确定自己的广告都展示在哪些设备上。他们应当查看下面哪个报告？

The correct answer is "Standard report with Platform Type dimension" because the Platform Type dimension in Campaign Manager 360 specifically categorizes impressions, clicks, and conversions by device type (e.g., desktop, mobile, tablet). This directly addresses the pet food store's need to see where their ads are being displayed across different devices. "Standard report with Cross-Device Conversions dimension" is incorrect because while cross-device conversions are important, this dimension focuses on conversions that occur across multiple devices, not the initial device where the ad was displayed. "Standard report with Same-Device Conversions dimension" is similarly incorrect as it focuses on conversions on the same device, not the device where the ad was served. "Standard report with Environment Type dimension" is too broad; Environment Type typically refers to web vs. app environments, not specific device types like desktop or tablet.
