The question asks for the minimum Snowflake edition that provides both multi-cluster warehouses and up to 90 days of Time Travel. According to Snowflake documentation and the community discussion consensus (with 100% agreement on C and upvoted comments), Enterprise Edition is the correct answer. Standard Edition only provides 1 day of Time Travel and lacks multi-cluster warehouses. Business Critical Edition offers these features but is a higher-tier edition than Enterprise. Premier Edition does not exist in Snowflake's current edition offerings. Therefore, Enterprise Edition is the minimum edition that includes both required features.
