Answer: Data classification

The question asks which Snowflake feature can be used to 'find' or 'discover' sensitive data. Data classification (Option B) is specifically designed for this purpose - it automatically scans and classifies data to identify sensitive information like PII, financial data, etc. Masking policies (Option A) are used to protect sensitive data after it has been identified, not to discover it. Row level policies (Option C) control access to rows based on user context. External functions (Option D) are for calling external services and unrelated to data discovery. The community discussion confirms this with 100% consensus on B, and the top comment explains that classification finds sensitive data while masking policies protect it after discovery.
