Which of the following is a valid password for a system with the default "Password must meet complexity requirements" setting enabled as part of the GPO Password policy requirements?

'The Cat Chased its Tail AII Night' contains only uppercase and lowercase letters - spaces are not counted as a special character category under Windows complexity requirements - satisfying only 2 of the required 3 categories.

'disk ACCESS failed' contains only uppercase and lowercase letters, and spaces do not count as special characters under the Windows complexity policy, so it meets only 2 of the required 3 character categories.

SETI@HOME contains only uppercase letters and a special character, satisfying only 2 of the required 3 character categories and therefore failing the complexity requirement.

SaNS2006 contains uppercase letters (S, N, S), at least one lowercase letter (a), and digits (2006), satisfying 3 of the 4 character categories required by the Windows 'Password must meet complexity requirements' GPO policy. It also meets the default minimum length of 6 characters, making it the only valid password among the choices.
