Answer: Access History

The question asks which Snowflake data governance feature supports auditing when a user query accesses column data. Access History (Option A) is the correct answer because it provides visibility into query execution and data access through the ACCESS_HISTORY view in Account Usage, allowing auditing of which columns were read by user queries. The community discussion strongly supports this, with multiple comments and upvotes confirming A as the correct answer. Options B (Data classification) and D (Object dependencies) are unrelated to auditing query access. Option C (Column-level security) focuses on restricting access rather than auditing it, making it less suitable for the auditing use case described.
