The client computers in your network run either Windows XP or Windows 7. All client computers are in a single Active Directory Domain Services （AD DS） organizational unit （OU） named MyClients. You install Windows Software Update Services （WSUS）. You create a Group Policy object （GPO） that enables automatic updates from the WSUS server， and you link the GPO to the MyClients OU. You place all client computers in a targeting group named MyClients. Testing reveals that a security update that is applicable to both Windows XP and Windows 7 causes a line-of-business application to fail on the Windows XP client computers. You need to ensure that the application runs on the Windows XP client computers and that the Windows 7 client computers receive the security update. What should you do？ （）
- A Remove the Windows 7 client computers from the MyClients targeting group. Approve the update for installation to the All Computers targeting group.
- B Remove the Windows XP client computers from the MyClients targeting group. Approve the update for installation to the All Computers targeting group.
- C Remove the Windows 7 client computers from the MyClients targeting group. Approve the update for installation to the Unassigned Computers targeting group.
- D Create a targeting group named MyXPClients beneath the MyClients targeting group. Move the Windows XP client computers to the MyXpClients targeting group. Approve the update for installation to the MyClients targeting group.
