The question requires selecting two true statements about Snowflake data sharing. Based on Snowflake documentation and the community discussion consensus (83% selected CD with the highest upvotes), options C and D are correct. C is true because Reader Accounts are specifically created by Data Providers to share data with external consumers who don't have Snowflake accounts. D is true because shared databases in Snowflake are read-only for consumers, preventing them from modifying the shared data. Option A is false because new objects aren't automatically shared; explicit sharing is required. Option B is false because not all database objects can be shared (e.g., some system objects are excluded). Option E is false because Reader Accounts are not charged for warehouse usage; the Data Provider bears the compute costs, as clarified in the discussion.
