I'm surprised nobody mentioned the option of the database instance not being stopped. That seems like a pretty obvious one to me. Rookie mistake, if you ask me.

I think the database instance not being stopped could also be a possible cause for the backup failure.

I agree with Teddy, DML operations can definitely cause a backup to fail.

Ha! I bet the developer who caused this backup failure is feeling pretty sheepish right now. Always remember, no tinkering during backups, folks!

Whoa, I almost went with C on this one. But you're right, B makes the most sense. Don't mess with the database structure while it's being backed up!

I think the correct answer is B. Performing DDL operations during the backup can definitely cause it to fail. Gotta be careful with that stuff!

I think the backup failed because DML operations were performed during the backup.
