17. Why and when must you enable row movement on a table before a flashback
operation? (Choose the best answer.)
A. Flashback Drop requires row movement, because all the rows in the table
will have different object numbers.
B. Flashback Query requires row movement, because the rows will have new
ROWIDs picked up from the undo segment.
C. Flashback Transaction requires row movement, because any affected rows
may be moved as the transaction is reversed.
D. Flashback Table requires row movement, because any affected rows may be
moved as the changes are reversed.
