You are working with JMS publish-subscribe operations.

What happens when a producer publishes a message to a topic for which a durable subscription exists but there are no subscribers available?

AThe publisher waits for a subscriber, who then consumes it. However, the publisher will time out if no consumer arrives within the given timeout period.

BThe publisher sends the message. However, it is never consumed because there wasn't anything listening when it arrived, regardless of the message timeout length.

CThe publisher successfully sends a message, which will be consumed later, once there is a subscriber, assuming the message hasn't timed out.

DThe message publisher is immediately notified about the lack of subscribers and can decide for itself if, and when, to resend.
