The question asks which Snowflake data governance feature supports tracking sensitive data for compliance, discovery, protection, and resource usage. Object Tagging (Option D) is the correct answer because it allows users to attach metadata tags to database objects, enabling categorization, classification, and management of sensitive data. This directly supports the stated use cases. Row access policies (Option A) control data access but do not inherently track or classify data. Data classification (Option B) is a broader concept but not a specific Snowflake feature for tracking. Object dependencies (Option C) track relationships between objects but are unrelated to sensitive data tracking. The community discussion unanimously supports Option D with 100% consensus and upvoted comments explaining that Object Tagging is designed for this purpose.
