Let's say a transaction begins, but the system fails after a number of checkpoints. Select the statement that best describes what happens in the recovery process when the server restarts. Since the transaction was not yet committed when it passed through the checkpoints, there is no need for the recovery to take any action The database changes made for this transaction from the checkpoint prior to the last must all be undone as part of the recovery process All modifications made to the database for the transaction at each prior checkpoint must be undone throughout the recovery process All modifications made to the database for this transaction by any process, including checkpoints, must be undone by the recovery process
