You are the administrator of a Windows 2000 Professional computer. The computer has three identical 4-GB hard disks. The disk and volume configuration of the computer is shown in the following table.  At the beginning of the new project, you want to configure the computer’s disks so that you can store 2.5 GB of new data. You want to ensure that you optimize the performance with which the 2.5 GB of data can be written to the disks.  Which two actions should you take?（）

• A、Convert both disk 1 and disk 2 to dynamic disks.
• B、Convert only disk 2 to a dynamic disk.
• C、Extend volume D to include the unallocated space on disk 1.
• D、Create a new spanned volume that contains the 1.5 GB of unallocated space on disk 1 and 1.5 GB of the unallocated space on disk 2.
• E、Create a new stripped volume that contains 1.5 GB of unallocated space on disk 1 and 1.5 GBof the unallocated space on disk 2.
