Answer - C - The CPU registers and the system RAM saved into a file on the hard drive are in the Hibernation state.

Key Takeaway: The Hibernation power management state writes the contents of your CPU registers and system RAM to a file on the hard drive. When the computer is restarted, it reloads the content of memory and is restored to the state it was in when hibernation was invoked. Hibernating and later restarting is usually faster than closing down, starting up, and starting all the programs that were running.
