The correct answer is C. F8.

The F8 key is a function key found on most computer keyboards. It is used to access the system boot menu, which allows you to choose which operating system to boot from. To access the system boot menu, press the F8 key repeatedly as soon as your computer starts up. You will see a list of operating systems appear

on the screen. Use the arrow keys to select the operating system you want to boot from, and then press Enter.

The other options are incorrect because they do not correspond to any known function keys.
