B,C Correct answer
Explanation

Entity beans represent persistent data stored in a database and can survive server crashes because their state persists in storage. Stateful session beans maintain conversational state with a specific client only in memory and lose that state if the server crashes. Session beans typically handle business logic and make calls on entity beans for data operations, not the reverse.
