Answer: B

Explanation:

Selective authentication between forests

If you decide to set selective authentication on an incoming forest trust, you need to manually assign permissions on each computer in the domain as well as the resources to which you want users in the second forest to have access. To do this, set a control access right Allowed to authenticate on the computer object that hosts the resource in Active Directory Users and Computers in the second forest. Then, allow user or group access to the particular resources you want to share.
