Which report, without additional configuration, shows e-commerce conversion rates for users on Tablets?

The Audience Mobile Overview report is the correct choice because it provides a quick summary of performance metrics, including e-commerce conversion rates, broken down by device category (desktop, mobile, tablet) without requiring any additional configuration. This report is designed to give an immediate insight into how different device types are performing. The Conversions Ecommerce Overview report shows overall e-commerce performance but doesn't segment by device type by default. Audience Cross-Device Device Paths shows the sequence of devices users employ, not conversion rates by device type. Audience Mobile Devices lists specific device models, but the Overview report is better for a high-level summary of conversion rates by device category.
