Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Database systems implement transactions as ACID units, and abnormal termination triggers an automatic rollback mechanism. This ensures atomicity: all changes made during the unit of work are undone, preventing partial or inconsistent data states. The transaction cannot remain active or move to pending states when the application unexpectedly terminates.
