The correct answer is: D. You finish working and going to bed.
When you choose the Sleep option, your computer will save your work and turn off the display and most of the hardware. This uses less power than shutting down your computer, and it allows you to resume your work quickly when you turn it back on.
The other options are not correct because:
- A. The computer is not tired after working for the whole day.
- B. If you are leaving for a very short time, you should choose the Hibernate option instead. This will save your work and turn off your computer completely, but it will use less power than shutting down your computer.
- C. If your computer gets hanged frequently, you should try to fix the problem instead of letting it sleep. You can try restarting your computer, updating your drivers, or running a virus scan.
