Answer: Named stage, User stage, Table stage

The question asks for the three types of internal stages in Snowflake. According to Snowflake documentation and the community discussion (with 100% consensus and upvoted comments), internal stages are stages managed by Snowflake that don't require external cloud storage credentials. The correct internal stages are: B (Named stage) - user-defined stages created in a schema, C (User stage) - personal stage for each user, and E (Table stage) - automatically created stage for each table. Option A (Schema stage) is not a valid Snowflake stage type. Option D (Stream stage) is incorrect as streams are for change data tracking, not file stages. Option F (Database stage) is not a valid internal stage type in Snowflake.
