问题：单选题An administrator has a two node cluster， Node1 and Node2， running resource group rg1. The resource groupis active on Node1. The administrator stopped cluster services and unmanaged the resource group on Node1to work on a problem. Now the administrator needs to move rg1 to Node2. Which of the following will achievethis？（）A Perform a clstart on Node1 with ’Manage Resource Groups’ set to ’Manually’ and select the destination ofNode2B Perform a resource group move operation from Node1 to Node2 and select the option to ’Re-manageResource Groups’ set to ’Automatically’C Perform a clstop on Node1 with option to move resource groups， this will release the resource group fromNode1 and accquire the resource group on Node2.D Perform a clstart on Node1 with ’Manage Resource Groups’ set to ’Automatically’， then perform a resourcegroup move operation to move rg1 from Node1 to Node2
