What Windows security object is granted the vCenter Server administrator role during installation?

The correct answer is C.

vCenter Server cannot be installled on a domain controller. vCenter Server can be installled on a member server. By default, all users who are members of the local Windows Administrators group on Windows Server are granted the same access rights as any user assigned to the Administrator role. Because the Domains Admins group is a member of a local Administrators group, this means that Domain Admins group is also given the Administrator role in vCenter Server.

It’s true that users who are in the Active Directory group ESX Admins are automatically assigned the Administrator role, but
the question says “during installation”.
