The question asks which activities can be monitored directly from Snowsight's Activity tab without using Account_Usage views. According to Snowflake documentation and the community discussion with 100% consensus (BC), the correct answers are Query History (B) and Copy History (C). These are directly accessible in the Activity tab's visual interface, providing immediate monitoring capabilities. Login History (A) requires querying LOGIN_HISTORY view in Account_Usage schema. Event Usage History (D) requires querying EVENT_USAGE_HISTORY view. Virtual Warehouse Metering History (E) requires querying WAREHOUSE_METERING_HISTORY view. Only Query History and Copy History offer direct monitoring through Snowsight's Activity tab interface.
