Answer: Object tagging

The question asks about a Snowflake governance feature that allows assigning metadata labels/tags to improve data governance and access control. Object tagging (Option C) is specifically designed for this purpose - it enables users to assign custom metadata tags to Snowflake objects, which can then be used for classification, tracking, and implementing access control policies. The community discussion shows 100% consensus on Option C with supporting documentation reference. Option A (Secure functions) and Option B (Secure views) are security features but don't involve metadata labeling. Option D (Row-level security) provides granular access control but doesn't focus on metadata tagging capabilities.
