Your network contains an Active Directory forest named contoso.com. The contoso.com
domain only contains domain controllers that run Windows Server 2012 R2.
The forest contains a child domain named child.contoso.com. The child.contoso.com domain
only contains domain controllers that run Windows Server 2008 R2. The child.contoso.com
domain contains a member server named Server1 that runs Windows Server 2012 R2.
You have access to four administrative user accounts in the forest. The administrative user
accounts are configured as shown in the following table.
You need to ensure that you can add a domain controller that runs Windows Server 2012 R2
to the child.contoso.com domain.

Answer = C
http://technet.microsoft.com/en-us/library/dd464018%28v=ws.10%29.aspx
adprep /forestprep must be run on the schema master for the forest
adprep /domainprep must be run on the infrastructure master for the domain
So the answer is C as this is the domain admin for the child domain.
The key to this question is that root domain already has 2012 DC’s, so there is no need to run adprep /forestprep which requires enterprise admins or root domain admins membership. You only have to prepare child domain.
