Answer: 30 days

The correct answer is C (30 days) based on Snowflake's official documentation and the community consensus. According to Snowflake's security documentation, all Snowflake-managed encryption keys are automatically rotated when they are more than 30 days old. This applies to internal stage encryption keys as well as other Snowflake-managed keys. The community discussion shows 100% agreement on answer C, with multiple users citing the official documentation that confirms the 30-day rotation policy. Options A (1 day), B (14 days), and D (120 days) are incorrect as they don't align with Snowflake's documented key rotation schedule.
