D Correct answer
Explanation

Stateful session beans maintain conversational state with a specific client. The correct answer is D because stateful session beans can receive initial state information through arguments in their create methods. Option A is incorrect because while there's a relationship, it's not accurately described as many-to-one. Option B is false because bean instances have a finite lifecycle. Option C is incorrect because the container doesn't arbitrarily discard stateful beans - passivation/activation follows specific rules. Option E is false because instances are created on client demand, not deployment.
