In your test database， you have created the ORDERS table as an index/x7forganized table （IOT）. To facilitate faster querying， you have created a mapping table and a bitmap index on the ORDER_FILLED column. You observe that the query performance degrades when users perform a large volume of transactions. While investigating the reason， you find that the mapping table segment is fragmented， leading to poor performance. Which option would you use to defragment the mapping table without affecting the original table data？（）A、export and import the mapping tableB、drop and recreate the mapping tableC、truncate the mapping table and reinsert the valuesD、use the ALTER TABLE .. REBUILD command to defragment the mapping table
