A: Reduces the redo generated. B: Allows DML over GTT even in read-only mode. E: Minimize use of undo tablespace.

B, D, E B: Undo tablespace is typically locked in read-only mode. Using temp undo allows DML operations to occur on global temporary tables even in a read-only database D: By using temp UNDO, the system avoids unnecessary writes to SYSTEM tablespace, which improves performance by reducing I/O operations E: Usage of UNDO space in the UNDO tablespace is minimized since the UNDO for DML operations is stored in temporary storage
