After upgrading the domain controllers, the next step is to raise the domain functional level. This is achieved by running the Set-ADDomainMode cmdlet in Windows PowerShell. The cmdlet must be run with the -Identity parameter specifying the FQDN of the domain and the -DomainMode parameter specifying the target functional level. In this case, the command would be Set-ADDomainMode -Identity domainA.com -DomainMode Windows2012R2Domain. Option A is incorrect because it sets the forest functional level, not the domain functional level. Option B is incorrect because it only retrieves information about the domain role holders. Option C is a command-line tool that can be used for managing domain membership and trust relationships, but it is not relevant for raising the domain functional level.
