Employees who demonstrate divided loyalty or allegiance to the u. s. may attempt to access sensitive information without what?

The answer is C) Authorization

To access sensitive government documents and data, there is a proper procedure that needs to be followed. This includes, getting the authorization of high ranked officials, who will give permission and authorize access to sensitive data.

In the past, employees of the US government, who have divide loyalties would access these documents without going through a proper authorization channel. 

This is a criminal offense and an act of treachery
