Answer:
B. Windows domain user name and password
Step-by-step explanation:
Windows domain user name and password are login credentials required for the user to successfully sign in to the Windows domain.
The domain username and password are usually stored on a domain controller rather than on the host.
As a domain user, the computer seeks from the domain controller the privileges assigned to the user, if it gets a positive response from the domain controller, it authorizes the users login credentials without restrictions; else, it denies the user access.
