At the request of a user， you issue the following command to restore a dropped table： flashback table "BIN$F2JFfMq8Q5unbC0ceE9eJg==$0" to before drop； Later， the user notifies you that the data in the table seems to be very old and out of date.  What might be the problem？（）  

• A、 Because a proper range of SCNs was not specified， the wrong data was restored.
• B、 A proper range of timestamps was not specified， so the wrong data was restored.
• C、 A previous Flashback Drop operation had been performed， resulting in multiple versions of the table being stored in the Recycle Bin.
• D、 Either option A or B could be correct. Not enough information was provided to determine which.
• E、 None of the above.
