Answer - B - You must be a group of the Enterprise Admins group to be able to create or modify an application directory partition.

Key Takeaway: An application directory partition is replicated only to specific domain controllers. A domain controller that participates in the replication of a particular application directory partition hosts a replica of that partition. Only domain controllers running Windows Server 2003 can host a replica of an application directory partition. To change any of the features in the application directory partition, you must be a member of the Domain Admins group or the Enterprise Admins group in Active Directory or you must have been delegated the appropriate authority.
