D Correct answer
Explanation

BES receives expired ACK (acknowledgment) messages from the BB relay after 7 days. This means that if a message has not been successfully delivered and acknowledged by the device within 7 days, the relay will send back an expired acknowledgment to the BES server. This timeout prevents indefinite waiting for message delivery confirmation.
