Answer: 365 days

The ACCESS_HISTORY view in Snowflake's Account Usage schema retains data for 365 days (1 year) in Enterprise Edition or higher. This is explicitly documented in Snowflake's official documentation and confirmed by the community discussion where all responses unanimously select option D with supporting references to the documentation. The other options (7 days, 14 days, 28 days) represent shorter retention periods that do not apply to ACCESS_HISTORY.
