Answer:
Hibernate mode creates a hibernation file on the local hard drive by saving the contents of the computer's RAM before entering a low-power state. Option (b) is true.
Step-by-step explanation:
In Hibernate mode, the contents of the computer's RAM (Random Access Memory) are saved to the hard drive before shutting down or entering a low-power state.
This is done to allow the system to resume its previous state quickly when powered back on.
When a laptop is not completely powered down and enters Hibernate mode, a hibernation file is created on the local hard drive to store the saved RAM contents.
This file is crucial for restoring the system to its pre-hibernation state upon the next power-up. In contrast, Sleep mode retains the system's state in RAM without saving it to the hard drive, and other options like Standby and Restart operate differently in terms of power management.
Thus, option (b) is true.
