Answer: Secure views

The correct answer is B (Secure views) because secure views in Snowflake can reference objects across multiple databases within the same account, allowing data providers to share data that resides in different databases. This is supported by the community discussion where all comments unanimously select B with 100% agreement, and references to Snowflake documentation confirm this capability. Other options are less suitable: A (External tables) are for accessing data outside Snowflake, C (Materialized views) are for performance optimization but don't inherently enable cross-database sharing, and D (UDFs) are for custom functions, not data sharing across databases.
