Explanation:

‘Administrators’ is a local group that provides full administrative access to an individual computer or a single domain, depending on its location. Because this account has complete access, you should be very careful about adding users to this group. To make someone an administrator for a local computer or domain, all you need to do is make that person a member of this group. Only members of the Administrators group can modify this account.
