Answer: Views, Tables

Dynamic Data Masking in Snowflake is a column-level security feature that applies masking policies to selectively obscure plain-text data at query time. According to Snowflake documentation and the community consensus (with multiple comments citing official sources and receiving upvotes), Dynamic Data Masking is supported on tables and views. Materialized views (B) are not supported because they store precomputed results, which conflicts with the dynamic, query-time nature of data masking. External tables (D) are not supported as they reference data outside Snowflake's control. Future grants (E) are irrelevant to data masking as they pertain to privilege management, not data obfuscation.
