Answer and explanation are below.

Answer is D. An Access is denied message when attempting to cleanup Active Directory metadata is most likely that the object is protected against accidental deletion.

Quick Tip: To prevent the error when using in Active Directory Sites and Services, right-click the domain controller or the NTDS Settings object, click Properties, click Object, and clear the Protect object from accidental deletion check box. When using Active Directory Users and Computers, the Object tab appears only after clicking View and then clicking Advanced Features.
