B Correct answer
Explanation

Stateful session beans maintain conversational state with specific clients across method invocations - the cached state represents that client's ongoing session. Stateless beans have NO affinity to clients - any instance can serve any client request, and any cached state is transient and not client-specific. Stateful beans are NOT about persistence.
