Answer: 7 days

According to Snowflake documentation, the Fail-safe period for permanent tables is 7 days. This is a fixed duration that cannot be changed by users. The community discussion confirms this with 100% consensus on option C, and references to official Snowflake documentation support this answer. Options A (1 day), B (3 days), and D (14 days) are incorrect as they do not match Snowflake's standard Fail-safe retention period for permanent tables.
