Answer - C - You should use the Secondary logon if you want to logon to a non-administrator account and run applications in the administrative mode.

Key Takeaway: Windows secondary logon allows administrators to log on with a non-administrative account and perform administrative tasks by running trusted administrative programs in administrative contexts. Although secondary logon is primarily intended for system administrators, it can be used by any user with multiple accounts to start programs under different account contexts without the need to log off. It is started automatically after a clean installation of Windows.
