FLASHBACK TABLE emp TO BEFORE DROP; INSERT INTO emp VALUES (2,COTT 10); INSERT INTO emp VALUES (3,ING 55);
A. Both the INSERT statements would fail because all constraints are automatically retrieved when the table is flashed back.
B. Both the INSERT statements would succeed because none of the constraints on the table are automatically retrieved when the table is flashed back.
C. Only the first INSERT statement would succeed because all the constraints except the primary key constraint are automatically retrieved after a table is flashed back.
D. Only the second INSERT statement would succeed because all the constraints except referential integrity constraints that reference other tables are retrieved automatically after the table is flashed back.
