Answer / guest
Answer: D
Since this is a real-time system the answer is a transaction

incurred to reenter transaction data if a transaction log
were not maintained. A transaction log also permits
operations personnel to determine which transactions have
been posted, and this helps to decrease recovery time when
system failures occur.
