某間國內寵物食品店正在電腦、手機和平板電腦上放送廣告活動，並想瞭解廣告顯示在哪些裝置上。 請問他們該查看哪種報表？

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 the type of device they occurred on (e.g., desktop, mobile, tablet). This directly addresses the pet food store's need to understand where their ads are displayed across different devices. "Standard report with Same-Device Conversions dimension" and "Standard report with Cross-Device Conversions dimension" are incorrect because these dimensions focus on conversion paths and whether conversions happened on the same device or across multiple devices, not simply where ads were displayed. "Standard report with Environment Type dimension" is incorrect because Environment Type refers to the context where an ad appears (e.g., web, app), which is different from the device type itself.
