Answer: Materialized views

Based on the community discussion and Snowflake documentation, materialized views (D) are supported by both database replication and replication groups. The community consensus strongly supports D with 86% of votes and multiple comments confirming that materialized views contain actual data and query results that need to be consistent across replicated databases. Pipes (A) are not supported by database replication (only by replication groups), as confirmed by multiple comments referencing Snowflake documentation. Users (B) are only supported by replication groups, not database replication. Stages (C) are also not supported by database replication (only by replication groups), as explicitly stated in the documentation references provided in the discussion.
