The correct answer is: A. press alt + Ctrl + delete, twice.
When a computer crashes, it is important to try to shut it down safely. Pressing Alt + Ctrl + Delete twice will bring up the Task Manager, which can be used to end the process that is causing the crash. If the Task Manager does not work, you can press the reset button on the computer. However, this should only be done as a last resort, as it can erase unsaved data. Turning off the computer and booting from a floppy disk is not necessary in this situation.
