B Correct answer
Explanation

Unit-of-Order is a WebLogic JMS feature that ensures messages are processed sequentially. When a message is actively being processed by a consumer, other messages in the same Unit-of-Order are blocked until the current message completes. This prevents out-of-order processing. Messages are not expired (A), delivered to other consumers (C), or rolled back (D) - they simply wait.
