You have a single Active Directory directory service domain. You have an application that adds Active Directory Schema attributes during installation. The attributes replicate as part of global catalog replication. Your user account is a member of the Domain Admins, Schema Admins, and Enterprise Admins global groups. You test the application and decide not to deploy it to production. You need to ensure that the attributes that are added by the application are no longer available in Active Directory. Using the Active Directory Schema snap-in, what should you do?

A.
Clear the Index this attribute in the Active Directory option for each attribute that is added by the application.

B.
Clear the Attribute is active option for each attribute that is added by the application.

C.
Clear the Replicate this attribute to the Global Catalog option for each attribute that is added by the application.

D.
Clear the Allow this attribute to be shown in advanced view option for each attribute that is added by the application.
