Answer: 30 Days

According to Snowflake documentation and the community discussion consensus (with 100% agreement and multiple upvoted comments referencing official documentation), all Snowflake-managed keys, including Account and Table master keys, are automatically rotated by Snowflake when they are more than 30 days old. This is a security best practice to regularly rotate encryption keys. The community discussion shows unanimous support for option A, with multiple users citing the official Snowflake documentation that confirms the 30-day rotation period. Options B (60 days), C (90 days), and D (365 days) are incorrect as they represent longer rotation periods than Snowflake's standard practice.
