  1. A Time the message stays locked
  2. B Time before an unprocessed message expires and moves to DLQ (if DL on expiry is enabled) (correct answer)
  3. C Maximum processing time allowed

Shortcut: TTL controls how long a message stays in the queue. After TTL, the message is expired and (if dead-lettering on expiry is enabled) moved to the DLQ.
