Answer: 5 minutes

The minimum configurable idle timeout value for a Snowflake session policy is 5 minutes. This is explicitly stated in Snowflake's official documentation and confirmed by the community discussion where all responses (100%) select option B with supporting references to the documentation. The default idle timeout is 240 minutes (4 hours) when no session policy is set, but the minimum configurable value that administrators can set is 5 minutes. Options A (2 minutes), C (10 minutes), and D (15 minutes) are incorrect as they do not match Snowflake's documented minimum value.
