The question asks for two characteristics of schemas in Snowflake. Option B is correct because in Snowflake's hierarchy, a database contains one or more schemas. Option C is correct because a schema logically groups related database objects like tables, views, and functions. Option A is incorrect as the relationship is reversed - databases contain schemas, not schemas containing databases. Option D is incorrect because schemas are not contained within virtual warehouses; warehouses provide compute resources independent of schema organization. Option E is incorrect because a table exists within a single schema and cannot span multiple schemas. The community discussion shows 100% consensus on BC with multiple users confirming this answer and referencing Snowflake documentation that supports these characteristics.
