Answer: 2 weeks

The correct answer is C (2 weeks) because the Snowflake documentation and community discussion consistently confirm that the Warehouse Activity section in Snowsight displays activity graphs with a default time period of 2 weeks. Multiple comments reference the official Snowflake documentation (https://docs.snowflake.com/en/user-guide/ui-snowsight-admin#warehouse-activity) which explicitly states '2 Weeks (default)' as the default period. The community discussion shows 100% consensus on answer C with upvoted comments providing direct documentation evidence. Options A (2 hours), B (1 week), and D (1 month) are incorrect as they represent other available time period options but not the default setting.
