You are the desktop administrator for your company. You are responsible for automating the deployment of Windows XP Professional to new computers in your company. You are preparing a Windows XP Professional computer, which you will use to test disk imaging. You install Windows XP Professional on the test computer and run the Sysprep utility. You use a third-party software package to create a disk image. You apply the disk image to a new computer and then restart the computer. Instead of completing the Windows XP Professional installation, the computer starts the Windows Welcome program, requiring you to enter additional setup information.  Because you will be deploying a large number of computers, you want to ensure that the disk image can be applied without additional user interaction. What should you do?（） 

• A、Use a network-based RIS server to apply the disk image to new computers. 
• B、On the test computer, run the Sysprep -factory command. Re-create the disk image by using the third-party software. 
• C、Use Setup Manager to create a Sysprep answer file. Copy the answer file to a floppy disk, and insert the disk into new computers when the disk image is applied. 
• D、Create an Unattend.txt answer file. Copy the file to the C:/Winnt/System32 folder on the test computer. Run the Sysprep utility and re-create the disk image by using the third-party software.
