Answer: Tags

The correct answer is A (Tags) because Snowflake's Object Tagging feature is specifically designed to track sensitive data for compliance, discovery, protection, and resource usage. As confirmed by the community discussion with 100% consensus and upvoted comments, tags allow users to classify and label sensitive data, which can then be used for data governance purposes including compliance tracking, data discovery, applying protection policies (like masking), and monitoring resource usage. The other options are less suitable: B (Comments) are for documentation purposes only, C (Internal tokenization) is not a Snowflake feature for data tracking, and D (Row access policies) are for controlling row-level access rather than tracking and classifying sensitive data.
