B
I also think the right answer is B.
Password Caching
When the timeout expires, the user will be asked to authenticate again. If password-caching is enabled, clients will supply the cached password automatically and the authentication will take place transparently to the user. In other words, the user will not be aware that re-authentication has taken place.
Password caching is possible only for multiple-use passwords. If the user’s authentication scheme implement one-time passwords (for example, SecurID), then passwords cannot be cached, and the user will be asked to re-authenticate when the authentication time-out expires. For these schemes, this feature should not be implemented.
Password caching is specified in the client’s Authentication window.
Other sites have their answer D: By installing Sec. Policy, even older version have the answer D
CONFUSING
Thre are two methods to clear: After a timeout AND a Policy install
Choice B has the word “ONLY” in it, so the answer should be D 🙂
