You administer a Windows 2000 Professional desktop computer. TKPrinter1 is a printer used by the engineering and research departments. The printer is shared from the Windows 2000 Professional computer that you administer. The engineering department frequently prints documents that are several pages in length， which takes a long time to print. Users in the research department who have small files to print often must wait a long time for their jobs to print. You want to reduce the time it takes for the user in research department to print their files. You want to accomplish this with the least amount of administrative effort.  What should you do？（）

• A、Monitor the print queue， and raise the priority of all the print jobs that are sent by users who are not members of the engineering department.
• B、Delete the old printer. Add a new printer， and set the priority to a higher value. Pause the print queue only when the engineering print jobs are printing.
• C、Configure the priority of TKPrinter1 to 50. Add a new printer， and set the priority to 1. For the new printer， deny Print permission for users in the engineering department.
• D、Configure the priority of TKPrinter1 to 50. Add a new printer， and set the priority to 70. For the new printer， deny Print permission for users in the engineering department.
