Answer - C - You should plan to use Last Known Good Configuration to return to the state the computer was in before adding the new drivers.

Key Takeaway: Last Known Good Configuration stores a copy of a system’s hardware configuration and driver settings taken from the system’s registry when the OS successfully boots. When the boot process fails, the OS can use the record of the Last Known Good configuration to perform a successful boot. This configuration record often comes in handy after the installation of new drivers or devices, which may cause system errors. Each time the OS successfully boots, it replaces the previous Last Known Good configuration record with the new one from the most recent successful boot.
