Answer: There is no Fail-safe period for these tables.

The question asks about the Fail-safe period duration for temporary and transient tables in Snowflake. According to Snowflake documentation and confirmed by the community discussion, temporary tables (which exist only for the duration of a session) and transient tables (which persist until explicitly dropped but don't have the same data protection features as permanent tables) do NOT have a Fail-safe period. Fail-safe is a data recovery feature available only for permanent tables, providing 7 days of protection after the Time Travel retention period ends. All community comments unanimously support answer A with 100% consensus, stating there is no Fail-safe period for these table types.
